Answer:

$10 + 4i$

Step-by-step explanation:

Original Equation:

$2\sqrt{25} + \sqrt{-16}$

Simplify sqrt(25)

$2*5+\sqrt{-16}$

Simplify multiplication

$10+\sqrt{-16}$

Split the radical -16 into two, using the identity: $\sqrt[n]{a} * \sqrt[n]{b} = \sqrt[n]{ab}$

$10 + \sqrt{-1}*\sqrt{16}$

Simplify the sqrt(16) and sqrt(-1) using definition of an imaginary number
