What is the solution to this equation? √x=7 a. x=√ 49 b. x=√7 c. x=14 d. x= 49

Let's not look at the option and try to solve it.
√x=7
Let's look at this. Square roots are the number that is multiplied by itself to make that number. For example, 2 is the square root of 4, 3 is the square root of 9.
We need to multiply 7 by itself to find x.
7×7=49
So, D. =49.

D.49 since the square root of 49 is 7
