I need the answer ASAP can anyone help?

Answer 1

Answer:
`3√(7)`

3*sqrt(7)

3 times the square root of 7

====================================================

Step-by-step explanation:

I'm assuming the V stands for square root. You can write sqrt(63).

`√(63) = √(9*7)\\\\√(63) = √(9)*√(7)\\\\√(63) = 3√(7)`

The idea is to factor 63 in such a way that one factor is the largest perfect square possible, that way we can pull the root apart to simplify as shown above. The rule I used for the second step is
`√(x*y) = √(x)*√(y)`
