Question

How do i do solve this math problem?

Answer 1

-3*5*7=-105
When a square root of an a expression is multiples by itself the result is that expression.

Answer 2

When you multiply two square roots together, you basically multiply the numbers within and put a squre root over that.

For example, in this case:

sqrt (5) * sqrt (5) = sqrt (25) = 5

Now that we have 5, we just multiply that to -3 and 7:

5 * -3 * 7 = -105

The answer is -105.
