Question
Simplify: $7 ^ { \frac { 1 } { 2 } } \cdot 8 ^ { \frac { 1 } { 2 } }$

Answer

$7 ^ { \frac { 1 } { 2 } } \cdot 8 ^ { \frac { 1 } { 2 } }$

We know that $a ^ { m } \cdot b ^ { m } = ( a \times b ) ^ { m }$.

So, $7 ^ { \frac { 1 } { 2 } } \cdot 8 ^ { \frac { 1 } { 2 } } = ( 7 \times 8 ) ^ { \frac { 1 } { 2 } }$

$= ( 56 ) ^ { \frac { 1 } { 2 } }$

Therefore, the value of $7 ^ { \frac { 1 } { 2 } } \cdot 8 ^ { \frac { 1 } { 2 } }$will be $( 56 ) ^ { \frac { 1 } { 2 } }$.
