Question

Typing up the question..

Answer 1

\[4a ^{3}b ^{2}\times3a ^{-4}b ^{-3}\]
Simplify.

Answer 2

\[12a ^{-1}b ^{-1}\]
Is it that?

Answer 3

Use the same rule as before. a^b * a^c = a^(b+c)
Then, use:
\[a^{-b} = \frac{1}{a^b}\]

Answer 4

Right so far.

Answer 5

So
\[12/ab\]

Answer 6

?

Answer 7

Yes.
\[\frac{12}{ab}\]
