We know that 64 is a perfect square of 8 because 8, when multiplied by itself, gives 64. Also, we must tell you that 64 is a rational number. So, bring your square root of numbers notes as in this article, we will find how to calculate the square root of 64 and solve some examples of the same.\u00a0<\/span><\/p>\n

Let\u2019s get started.<\/span><\/p>\n

Square root of 64<\/span><\/h2>\n

8 is the square root of 64 because 8 x 8 gives 64. Hence, if we inverse this operation, we get <\/span>\u221a64 = 8. The value of the square root of 64, i.e., 8 can be positive or negative. In this article, we will only consider the positive value of root 64.\u00a0<\/span><\/p>\n

How to find the square root of 64?<\/span><\/h3>\n

There are many different methods to find the value of \u221a64. Since we know that it is a perfect square number, we can find its square root using the prime factorisation method.\u00a0<\/span><\/p>\n

64 is a composite number. Its factors are 1, 2, 4, 8, 16, 32, and 64.<\/span><\/p>\n

Let us first find the prime factors of <\/span>64<\/span>.<\/span><\/p>\n

Upon factorisation, we get 64 = 2 x 2 x 2 x 2 x 2 x 2.\u00a0<\/span><\/p>\n

So, <\/span>\u221a64 = \u221a(<\/span>2 x 2 x 2 x 2 x 2 x 2)<\/span><\/p>\n

The factors include three pairs of number 2; therefore, we can consider each pair as one number to do away with the square root.<\/span><\/p>\n

\u221a64 = <\/span>2 x 2 x 2\u00a0<\/span><\/p>\n

\u221a64 = 8<\/span><\/p>\n

Furthermore, 64 is a perfect square and 8 x 8 = 64. So, we can also find the root of 64 by another method, i.e., by inversing the squaring operation.\u00a0<\/span><\/p>\n

\u221a64 = \u221a8<\/span>2<\/sup><\/span><\/p>\n

= 82*(1\/2)<\/sup><\/span>\u00a0<\/span><\/p>\n

= 8<\/span><\/p>\n

So, \u221a64 is 8.\u00a0<\/span><\/p>\n

Let us look at the root in correlation with power.<\/span><\/p>\n

Consider the number’ a’ and a natural number ‘x.’\u00a0<\/span><\/p>\n

Then, a<\/span>x<\/sup><\/span> = a * a * a \u2026\u2026 (multiplied ‘x’ number of times)<\/span><\/p>\n

If the value of \u2018x\u2019 is 2 and \u2018a\u2019 is 4, then 4<\/span>2<\/span> = 4 x 4 = 16<\/span><\/p>\n

This means, ‘4 raised to the power 2’ is 16.<\/span><\/p>\n

Now, the root is the inverse of power. Therefore, we can also see that 8, when multiplied by itself, gives 64. Hence, if 64 is the square of 8 then 8 is the value of root 16.<\/span><\/p>\n

<\/h2>\n

Is the \u221a64 rational or irrational?<\/span><\/h2>\n

If a number terminates at some point or has a repeating pattern in its decimal part. Then <\/span>it can be represented as a fraction with a non zero denominator. Such numbers are rational numbers<\/span>. Here, we can see that the value of \u221a64 is 8, i.e., a whole number. So, it is a rational number.\u00a0<\/span><\/p>\n
