A) $\left( m ^ { 2 } + k ^ { 2 } \right) ^ { 2 }$
B) $m ^ { \frac { 3 } { 2 } } + k ^ { \frac { 3 } { 2 } }$
C) $( m + k ) ^ { \frac { 1 } { 2 } }$
D) $\left( m ^ { 2 } + k ^ { 2 } \right) ^ { \frac { 1 } { 2 } }$
E) $( m + k ) ^ { \frac { 3 } { 2 } }$

Question

Quizplus · Accepted Answer

The square root symbol means the expression inside the radical is raised to the 1/2 power, so $\sqrt { m ^ { 2 } + k ^ { 2 } } = (m^2+k^2)^{\frac{1}{2}}$. Therefore, the correct choice is D.
