The simplified expression is -18x^6 * y^12.
Answered by GPT 3.5
When multiplying numbers with the same base, the exponents are added.

So,

178^5 * 178^9 = 178^(5+9) = 178^14

To simplify the expression, we'll first evaluate the terms inside the parentheses:

2√2^2 = 2√4 = 2(2) = 4

Now we can substitute this value back into the expression and simplify further:

3√64 + 3(4 + 5) = 3√64 + 3(9) = 3(8) + 3(9) = 24 + 27 = 51

Therefore, the simplified expression is 51.

I apologize for the mistake in my response. Upon reevaluating the expression, I realize that I made an error.

The correct simplification of the expression is:

3√64 + 3(2√2^2+5)
= 3√64 + 3(2√4+5)
= 3√64 + 3(2(2)+5)
= 3√64 + 3(4+5)
= 3√64 + 3(9)
= 3(8) + 3(9)
= 24 + 27
= 51

Therefore, the correct answer is 51.

Apologies for the confusion. The simplified expression is 31.

3√64 + 3(2√2^2+5) simplifies to 3*4 + 3(2*2+5) = 12 + 3(4+5) = 12 + 3*9 = 12 + 27 = 39.

Therefore, the correct answer is 39, which is not one of the options given.
