Chapter 7: Q13. (page 460)

Simplify each expression.
$(- 4 a b^{4}) (- 5 a^{5} b^{2})$

Short Answer

Expert verified

The expression $(- 4 a b^{4}) (- 5 a^{5} b^{2})$ can be simplified as $20 a^{6} b^{6}$ .

Step by step solution

Step 1. Group the coefficients and the variables.

Group the coefficients and variables in the given expression.

$(- 4) \cdot (- 5) (a \cdot a^{5}) (b^{4} \cdot b^{2})$

Step 2. Write the property of product of powers.

For any real number a and any integers m and n, $a^{m} \cdot a^{n} = a^{m + n}$ .

Step 3. Apply property of product of powers.

Apply the property of product of powers to the expression obtained in step 1.

$(4 \cdot 5) (a^{1 + 5}) (b^{4 + 2})$

Step 4. Simplify obtained expression.

Simplify the obtained expression in step 3.

$20 a^{6} b^{6}$

Therefore, $(- 4 a b^{4}) (- 5 a^{5} b^{2})$ can be simplified to $20 a^{6} b^{6}$ .
