Simplify and rewrite each expression

EndersWorld:

(5a^3)(-3a^-4)

EndersWorld:

There aren’t any

EndersWorld:

\[\left( 5a ^{3} \right)\left( -3a ^{-4} \right)\]

EndersWorld:

It’s the same thing XD

EndersWorld:

Kinda

Zowie:

I was wrong. You wouldn't use FOIL or distributive. Just give me one second to write it out.

Shadow:

\[(5a ^{3})(-3a ^{-4}) = (5a ^{3})(\frac{ -3 }{a ^{4} })\]

Shadow:

What do you think you would do next?

Shadow:

By the way, the exponent rules goes like this. \[x ^{-n} = \frac{ 1 }{x ^{n} }\]

Shadow:

@EndersWorld Do you know what you would do next in the problem?

Shadow:

\[(5a ^{3})(\frac{ -3 }{a ^{4} }) = \frac{ -15a ^{3} }{ a ^{4}}\]

Shadow:

\[\frac{ -15a ^{3} }{ a ^{4}} =\frac{ -15 }{a }\]

Shadow:

Let me know if you have any further questions.
