Answer:

{7}^{ \frac{3}{2} }

Step-by-step explanation:

\sqrt{7}  \: can \: also \: be \: written \: as \:  {7}^{ \frac{1}{2} }

We can use this information to rewrite the original expression:

7 \times  {7}^{ \frac{1}{2} }

7 can also be written as

{7}^{1}

Remember that when multiplying exponents, if they have the same base, we can add the exponents. Therefore:

{7}^{1}  \times  {7}^{ \frac{1}{2} }  \\  {7}^{1 +  \frac{1}{2} }  \\  {7}^{1 \frac{1}{2} }   \\  {7}^{ \frac{3}{2} }
