bet you got the idea now. write it without the negative exponents. then clear the fractions

\[\frac{5^{4}  5^{6}}{5^{3} +5^{5}}\] muttiply top and bottom by \[5^6\]

I got (1/5^4  1/5^6)/ (1/5^3 +1/5^5)

Cutiepo0Best ResponseYou've already chosen the best response.0
wait. How come I have to multiply top and bottom by 5^6?

satellite73Best ResponseYou've already chosen the best response.0
that will clear the fractions. \[5^{4}\times 5^6=5^2\]

if you want you can write this in fraction notation. then you will see that you should multiply top and bottom by \[5^6\]

i will write it out if you like

\[\frac{5^21}{5^3+5}\] is the second line clear?

i added the exponents, and i chose \[5^6\] so that they would all be positive
 2 years ago

satellite73Best ResponseYou've already chosen the best response.0
because i want to evaluate the numbers, i need the exponents to be positive
 2 years ago

satellite73Best ResponseYou've already chosen the best response.0
now i can see what the numbers are. numerator is 25+1=26

satellite73Best ResponseYou've already chosen the best response.0
denominator is 125+5=130

Cutiepo0Best ResponseYou've already chosen the best response.0
Isn't the numerator 251?

Okay, that's great, thanks :) I was making it way more complicated thn it needed to be

i would like to say that was a "typo" but i guess it was a mistake. in any case you have the answer, it is \[\frac{24}{130}=\frac{12}{65}\]
