Question

simplify the expression.

(9^4y^5)(-2x^2y^7)

Answer 1

so whats the answer

Answer 2

wrong

Answer 3

simplify the expression.
(9^4y^5)(-2x^2y^7)

18x^6y^12

7x^8y^12

-18x^6y^12

-18x^8y^12

Answer 4

When multiplying, we can combine the like variables by adding their exponents.
So (9^4y^5)(-2x^2y^7) simplifies to:
= 9^4 * -2 * x^2 * y^(5+7)
= 6561 * -2 * x^2 * y^12
= -13122x^2y^12

Answer 5

The simplified expression is -13122x^2y^12.

Answer 6

Apologies for the mistake. Let's simplify the expression correctly.

(9^4y^5)(-2x^2y^7)

When multiplying, we can combine the like variables by adding their exponents.

= (9^4 * -2) * (x^2) * (y^(5+7))

= (6561 * -2) * (x^2) * (y^12)

= -13122 * x^2 * y^12

Therefore, the simplified expression is -13122x^2y^12.

Answer 7

To simplify the expression (9^4y^5)(-2x^2y^7):

When multiplying exponentials, we add their exponents. Therefore, we have:

(9^4 * -2) * (x^2 * x^0) * (y^5 * y^7)

Simplifying further:

(-2) * (x^2) * (y^12)

Combining the coefficients and variables:

-2x^2y^12

Therefore, the simplified expression is -2x^2y^12.
