 \Large \fbox \red {Question \: :}

Find the value of n.

 {5}^{ - 5}  \times  {5}^{2n + 1}  =  {5}^{13}  \div  {5}^{7}

 \Large \fbox \red {Answer \: :}

 {5}^{ - 5} \times  {5}^{2n + 1}  =  {5}^{13}   \div  {5}^{7}

 {5}^{2n - 4}  =  {5}^{6}

Put the powers equivalent since the base is same.

2n - 4 = 6

2n = 6 + 4

2n = 10

n =  \frac{10}{2}

n = 5

 \implies So, the value of n is 5.
