What is the solution to this equation? √x=7 A. x=√ 49 B. x=√7 C.x=14 D. x= 49

IgorLugansk [536]

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.
