Question

Simplify 5s^-7/10s^-9

Answer 1

Simply cancel the common factor of 5 to get...

`(s^-7)/(2s^-9) \ \textgreater \ Apply exponent rule \ \textgreater \ (x^a)/(x^b) = x^(a - b) \ \textgreater \ (s^-7)/(s^-9) = s^(-7 - (-9)) = s^2 \ \textgreater \ (s^2)/(2)`
Therefore our final answer is.

`(s^2)/(2)`
