Question

6x^2/7x^4

Answer 1

\[\frac{a^b}{a^c}=a^{b-c}\]
so you have
\[\frac{6x^2}{7x^4}=\frac{6}{7}\frac{x^2}{x^4}=\frac{6}{7}x^{2-4}=\frac{6}{7}x^{-2}=\frac{6}{7x^2}\]

Answer 2

i dont understand

Answer 3

which part?

Answer 4

do you understand that
\[\frac{6x^2}{7x^4}=\frac{6}{7}*\frac{x^2}{x^4}\]?

Answer 5

yeah

Answer 6

ok well now we just use the property i showed
when we \[\frac{x^a}{x^b}=x^{a-b}\]so
\[\frac{x^2}{x^4}\space becomes\space x^{2-4}=x^{-2}=\frac{1}{x^2}\]

Answer 7

ok

Answer 8

example:
\[\frac{2^3}{2^2}=2^{3-2}=2\]
