A. 5.9
B. 5.3
C. 9.2
D. 7.1

Answer 1

Hello!

To look for squareroots, we need to find a solution for us that can help us solve the problem.

The most common way to solve for a squareroot is by factoring.

If this case, we can see that D. 7.1 is the closest approximation to the root of 51.

Answer 2

D.) 7.1 is the best approximation of the root 51 as the root of 51 is 7.1414 and so on!
