Please help…but please do explain how you come about the answer. I have two problems I am stuck on…?
Rule: Simply each, assume that the variable is positive.
Let “V” represent the square root symbol.
a. 3 / V x
b. -7 / V y
I tried multiplying a by the square root of x over the square root of x, and I got 3 V x over x and didn’t know where to go from there. Since I’m not sure if I’m on the right track, I have not yet tried problem b.
Thank you.

Just do the opposite.
a. 3√x
3² (which means 3×3) is the opposite of √, which means it is equal to the unknown variable, x
3²=x
Solve 3² to get x
9=x
b. -7√y
-7² (which means -7x(-7)) is the opposite of √, which means it is equal to the unknown variable, y
-7²=y
Solve -7² to get y
49=y
Hope you understand it now 🙂
