Question

Simplify (12q^3r^2)(4qr^4)

Answer 1

You need to know the index rule:
\[a^m\times a^n=a ^{m+n}\]
In your case:
\[12q^3\times r^2\times 4q\times r^4\]
Group all the Qs together and all the Rs together and apply the index rule

Answer 2

so the answer would be 48q^4r^6?

Answer 3

yes :)

Answer 4

okay, thanks.

Answer 5

Something a bit ambiguous in the question: is it 4qxr^4 or (4qr)^4?

Answer 6

4q*r^4

Answer 7

Yes then your answer is correct :)
