Question

Divide 20a5b3 by 5a2b. 4a3b2 4a3b3 4a3b4 4a7b4

Answer 1

4a^3b^2 ---->
`=4a^3b^2` So (A)

Explanation:

`(20a^5b^3)/(5a^2b)`

`\mathrm{Factor\:the\:number:\:}\:20=5\cdot \:4`

`=(5\cdot \:4a^5b^3)/(5a^2b)`

`\mathrm{Cancel\:the\:common\:factor:}\:5`

`=(4a^5b^3)/(a^2b)`

Simplify

`=(4a^3b^3)/(b)`

and simplify one more time!

`=4a^3b^2`

hope this helps ~~wdfadss~~

Answer 2
