Question

If the square root of n is approximately equal to 4.2, then n is between _____.

4 and 5
16 and 25
8 and 9
2 and 3

Answer 1

16 and 25

Explanation:

Answer 2

16 and 25

Explanation:

Given that the square root of n = 4.2, let's find an expression for this, then find the possible value of n.

Thus:

`√(n) = 4.2`

Solve for n. Square both sides.

`(√(n))^2 = (4.2)^2`

`n = 17.64`

Therefore, if the sqrae root of n was approximately equal to 4.2, then we can conclude that n is between 16 and 25.
