Question

simplify and write in exponential form with negative exponent​

Answer 1

=$2^{-1}\left[\left(\dfrac{5}{3}\right)^{4}+\left(\dfrac{3}{5}^{-2}\right) \right]$

=$\dfrac{1}{2}[(\dfrac{5}{3}^{4})+(\dfrac{5}{3}^{2}) ]$

$\large\red{\boxed{\blue{a^{-m}=\dfrac{1}{a}^{m}}}}$

Answer 2

=$2^{-1}\left[\left(\dfrac{5}{3}\right)^{4}+\left(\dfrac{3}{5}^{-2}\right) \right]$

=$\dfrac{1}{2}[(\dfrac{5}{3}^{4})+(\dfrac{5}{3}^{2}) ]$

$\large\red{\boxed{\blue{a^{-m}=\dfrac{1}{a}^{m}}}}$
