Simplify the square root of 3 times(the square root of 6 plus the square rooot of 15)

Okay so the square root of 6 would be either 3 or 2 because 3×2=6

And the square root of 15 would either be 3 or 5

because 3×5=15

And I don't understand when it says simplify the square root 3 times.

Hey!  The answer is 5

I use OW

have a good day ;)

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
