Answer:

Step-by-step explanation:

(1)     RHS=(\frac{4}{3}) ^{9}, therefore at LHS, value of 2x+1=9\\

     implies x=4.

(2)    (\frac{2}{5} )^{3}×(\frac{2}{5} )^{6}=(\frac{2}{5} )^{3+6} =(\frac{2}{5} )^{9}

     implies 3x=9,\ x=3

(3)    -(\frac{1}{5} )^{20}÷-(\frac{1}{5} )^{15}=-(\frac{1}{5} )^{20-15}

                              =-(\frac{1}{5} )^{5}.

(4)  \frac{1}{16} can be written as (\frac{1}{2} )^{4}

      therefore  (\frac{1}{2} )^{4}×(\frac{1}{2} )^{2}=(\frac{1}{2} )^{6}

      implies
