Question

Simplify: (−2a^2b)(4a^5b^2) need this quick thanks <3

Answer 1

Assignment:
`\bold{Simplify \ Equation: \ \left(-2a^2b\right)\left(4a^5b^2\right)}`

<><><><><>

Answer:
`\bold{-8a^7b^3}`

<><><><><>

Explanation:
`\downarrow\downarrow\downarrow`

<><><><><>

[ Step One ] Remove Parenthesis (a) = a

`\bold{-2a^2b\cdot \:4a^5b^2}`

[ Step Two ] Multiply Numbers:
`\bold{2\cdot \:4=8}`

`\bold{-8a^5a^2b^2b}`

[ Step Three ] Apply Exponent Rules

Note:
`\bold{Exponent \ Rules: \ a^b\cdot \:a^c=a^(b+c)}`

`\bold{a^5a^2=\:a^(2+5)=\:a^7}`

<><><><><>

`\bold{-8a^7b^2b}`

[ Step Four ] Apply Exponent Rule

Note:
`\bold{b^2b=\:b^(1+2)=\:b^3}`

`\bold{-8a^7b^3}`
