Answer 2

The given number is 3 √65.

To find :

The approximate value of 3 √65.

Solution :

• We see that 65 is not a perfect square.

A perfect sqaure is a number which has two equal factors.

• Here, we have to find the approximate value of 3 √65. So, we can consider the square number closest to 65.

• The square number closest to 65 is 64. The two equal factors of 64 are 8 and 8.

• Therefore, 3 √65 can be written as 3 √64.

Now, 3 √64 = 3 √(8 × 8)

= 3 × 8

= 24

∴ The approximate value of 3 √65 is 24.
