sqrt(x) * 7sqrt(x)

7 x

are you sure it isnt 7x^2 because you woulb be multply a x*7x =7x^2 or am i wrong

7 * x^.5 * x^.5 = 7 * x^1 = 7 x

To simplify the expression sqrt(x) * 7sqrt(x), we can apply the properties of radicals.

Step 1: Multiply the coefficients (numbers outside the square roots). In this case, the coefficients are 1 and 7, so the product is 7.

Step 2: Multiply the radicands (numbers inside the square roots). In this case, the radicands are x and x, so the product is x^2.

Therefore, the simplified expression is 7x^2.
