Question

(6/x^3) + (4/5x^5)

Answer 1

\[\frac{5}{x^3}+\frac{4}{5x^5}\]
your denominator will be \[5x^5\] so you musts multiply the first fraction top and bottom:\[\frac{5}{x^3}\times \frac{5x^2}={5x^2}\frac{25x^2}{5x^5}\]

Answer 2

oops
\[\frac{6}{x^3}\times \frac{5x^2}{5x^2}=\frac{30x^2}{5x^5}\]

Answer 3

now add the numerators:\[\frac{30x^2}{5x^5}+\frac{4}{5x^5}=\frac{30x^2+4}{5x^5}\]
