simplify the following radical expression: sqrt x * sqrt x

a) x
b) sqrt x
c) 2
d) no solution exists

do you know any site that will help me with the square roots? thanks!

The definition of sqrt(x) when it is squared (multiplied by itself), it gives x, or

√x * √x = x

thanks jen and mathmate

To simplify the given radical expression sqrt(x) * sqrt(x), we can use the property of square roots that says sqrt(a) * sqrt(b) = sqrt(ab).

So, sqrt(x) * sqrt(x) simplifies to sqrt(x * x), which is the same as sqrt(x^2).

Since the square root (√) undoes the squaring operation (^2), the expression simplifies to just x.

Therefore, the correct answer is option a) x.
