So, In this article, we are going to learn a trick to find the cube root easily. This trick will help us in verifying our answer when the question demands a particular method to solve the question.<\/p>\n
<\/p>\n
To find the cube root of any number with this trick, you only need to remember the cubes of the numbers from 1 to 10. Let us learn this trick with the help of the number \u201815625\u2019.<\/p>\n
<\/p>\n
13<\/sup> = 1<\/p>\n 23<\/sup> = 8<\/p>\n 33<\/sup> = 27<\/p>\n 43<\/sup> = 64<\/p>\n 53<\/sup> = 125<\/p>\n 63<\/sup> = 216<\/p>\n 73<\/sup> = 343<\/p>\n 83<\/sup> = 512<\/p>\n 93<\/sup> = 729<\/p>\n 103<\/sup> = 1000<\/p>\n <\/p>\n So, we can learn this trick with the help of the number \u201815625\u2019. We need to follow some steps to get the root of this number.<\/p>\n <\/p>\n STEP 1<\/strong> – Look at the unit digit of 15625, which is 5.<\/p>\n STEP 2<\/strong> –\u00a0 Now, we need to see the cubes of numbers \u20181 to 10\u2019 and see the cube of which number has \u20185\u2019 in its units place. We can see that the cube of \u20185\u2019 is \u2018125\u2019 and it has 5 in its unit place.<\/p>\n This helps in getting the unit digit of the cube root of 15625, which is 5.<\/p>\n STEP 3<\/strong> – Look at the number 15625, ignoring the last three digits of the number from the unit place, we are left with 15.<\/p>\n STEP 4<\/strong> – Now, We have to find two numbers between the cubes of which 15 lies. As per the list above, 15 lies between 8 and 27. They are cubes of 2 and 3 respectively. So, the required numbers, in this case, are 2 and 3.<\/p>\n STEP 5<\/strong> – We have to choose between 2 and 3 which will be placed in the tenth place of the cube root of 15625, so we will always choose the smaller number which is \u20182\u2019 in this case.<\/p>\n Hence, we get the cube root of 15625, which is 25. In this way, we can find many other cube roots without using the longer methods.<\/p>\n We can find the cube root of a \u20184-digit number to a 6-digit number\u2019 easily from this process.<\/p>\n But, for a 7-digit number, we need to remember the cubes of the number from 11 to 20 because the cube root of a 7-digit number is a 3-digit number. Then, we can follow all the steps mentioned above. For \u2018STEP 5\u2019 above, we need to find the two-digit number from 11 to 20, which will be placed in the tenth and hundredth place.[\/et_pb_text][\/et_pb_column][et_pb_column type=”2_5″ module_id=”stickysideR” admin_label=”Column R” _builder_version=”4.10.4″ _module_preset=”default” background_color=”#fdefe0″ custom_padding=”25px|25px|25px|25px|true|true” sticky_position=”top” sticky_offset_top=”-280px” sticky_limit_top=”row” sticky_limit_bottom=”row” sticky_position_tablet=”none” sticky_position_phone=”none” sticky_position_last_edited=”on|desktop” sticky_limit_bottom_tablet=”” sticky_limit_bottom_phone=”” sticky_limit_bottom_last_edited=”on|phone” border_radii=”on|15px|15px|15px|15px” box_shadow_style=”preset3″ global_colors_info=”{}”][et_pb_image src=”https:\/\/eistudymaterial.s3.amazonaws.com\/1080×1080.png” alt=”Free Trial banner” title_text=”Mindspark Free Trial Banner” url=”https:\/\/mindspark.in\/free-trial” align=”center” module_class=”adsimg” _builder_version=”4.11.1″ _module_preset=”default” custom_padding=”||||false|false” border_radii=”on|10px|10px|10px|10px” global_colors_info=”{}” transform_styles__hover_enabled=”on|hover” transform_scale__hover_enabled=”on|hover” transform_translate__hover_enabled=”on|desktop” transform_rotate__hover_enabled=”on|desktop” transform_skew__hover_enabled=”on|desktop” transform_origin__hover_enabled=”on|desktop” transform_scale__hover=”102%|102%”][\/et_pb_image][et_pb_text admin_label=”Explore Other Topics [\/et_pb_text][et_pb_text _builder_version=”4.10.7″ _module_preset=”default” text_line_height=”2.2em” link_font_size=”16px” custom_margin=”||0px||false|false” custom_padding=”10px|15px|10px|28px|true|false” locked=”off” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text admin_label=”Related Concepts [\/et_pb_text][et_pb_text _builder_version=”4.13.1″ _module_preset=”default” text_line_height=”2.2em” link_font_size=”16px” custom_margin=”||0px||false|false” custom_padding=”10px|15px|10px|28px|true|false” locked=”off” global_colors_info=”{}”]<\/p>\nCUBE ROOT OF 15625<\/strong><\/h2>\n
