Question

Simplify: (−2a2b) • (4a5b2)

Answer 1

(−2a^2b) • (4a^5b^2)

-2 *4 * a^2 * a^5 * b*b^2

multiply the numbers add the exponents

-8 a^6 b^3

Answer 2

Answer:
`-8a^7\ b^3`

Explanation:

Given expression :
`(-2a^2b)\cdot(4a^5b^2)`

`=-2*4* a^2*  a^5* b* b^2`

The product law of exponent :-

`x^n* x^m=x^(n+m)`

Using the product law of exponent for the given expression we have:-

`=-8* a^(2+5)* b^(1+2)\\\\=-8a^7\ b^3`

Thus , the given expression is simplified as
`-8a^7\ b^3`
