Simplify

\(\left(2x+10\right)^4\left(x+5\right)^4=\left(\left(2x+10\right)\left(x+5\right)\right)^4\)

\(\left(\left(2x+10\right)\left(x+5\right)\right)^4=\left(2x+10\right)^4\left(x+5\right)^4\)

\(\left(2x+10\right)^4\left(x+5\right)^4\) is your answer

\((2x+10)^4(x+5)^4\)

\((2(x+5))^4(x+5)^4\)

\(16(x+5)^4(x+5)^4\)

\(\color{brown}\boxed{16(x+5)^8}\)
