Question

Find the indicated roots.
√144x²y²

Answer 1

12xy

Explanation:

`√(144x^2y^2)`

The exponents of x and y cancel out (since squaring a number and then finding the square root of it is just the base of the exponent before squaring).

`√(144) xy`

Two numbers that multiply to 144 and are identical is 12 (12 x 12 = 144).

So, the answer is:

12xy
