Question

Which of the following is closer to 8
√61
√62
√65
√66

Answer 1

If you mean closer it can be √62 cuz this equals to 7.87
√65=8.06
√66=8.12

Answer 2

√65

Explanation:

We know that √64 is 8

So, the square root of the number closest to 64 in the list will be the closest to 8

In the List, √62 = √(64-2) [difference of 2]

√65 = √(64 + 1) [difference of 1]

Since √65 has the least difference from √64, we can say that √65 will be the closest to 8 in the given list
