Simplify the expression. (9x ^ 4 * y ^ 5)(- 2x ^ 2 * y ^ 7)
18x ^ 6 * y ^ 12
7x ^ 8 * y ^ 12
- 18x ^ 6 * y ^ 12
- 18x ^ 8 * y ^ 12
The simplified expression is -18x^6 * y^12.
Simplify. Express your answer as a single term using exponents.(1 point)
178^5 * 178^9
178^5 * 178^9 = ?
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.
choose one of the answers
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.
thats wrong choose one of the answers givin
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.
