Simplify by combining like radicals. The variable represents a positive real number. $4 \sqrt { 2 x } + 6 \sqrt { 2 x }$
A) $10 \sqrt { x }$
B) $10 \sqrt { 2 x }$
C) $2 \sqrt { 2 x }$
D) $24 \sqrt { 2 x }$
E) $20 \sqrt { x }$

Question

Quizplus · Accepted Answer

Since both terms have the same radical part, $\sqrt{2x}$, you can add their coefficients. $4 + 6 = 10$, so the simplified expression is $10\sqrt{2x}$.
