Question

Zero and negative exponents question...

Answer 1

What is the simplified form of \[3a ^{4}b ^{-2}c ^{3}\]

Answer 2

just need to remember this rule :
\[a^{-n} = \dfrac{1}{a^n}\]

Answer 3

\[3a ^{4}b ^{-2}c ^{3} = \dfrac{3a ^{4}c^{3}}{b^2}\]

Answer 4

I'm confused on how you got from \[a ^{-n}=\frac{ 1 }{ a ^{n}}\] to that

Answer 5

you're not alone, you're expected to be confused a bit when you encounter it for the first time

watch this short video to get some intuition on that rule

Answer 6

Thank you very much! All of these videos are exactly what I've been trying to find. @ganeshie8
