    Step-by-step explanation:

    Given equation

    (\sqrt[3]{3/5})^{2x+1}=125/27

    then simplify the equation

    \left ( 3/5 \right )^{(2x+1)/3}=\left ( 5/3 \right )^{3}

    convert same base form \left ( a/b \right )^{m}=\left ( b/a \right )^{-m}

    \left ( 3/5 \right )^{(2x+1)/3}=\left ( 3/5 \right )^{-3}

    if base is same then compare the power and find out the value of x

    \left ( 2x+1 \right )/3=-3

    2x+1=-9

    2x=-10

    x=-5
