Answer:

[tex]10 + 4i[/tex]

Step-by-step explanation:

Original Equation:

[tex]2\sqrt{25} + \sqrt{-16}[/tex]

Simplify sqrt(25)

[tex]2*5+\sqrt{-16}[/tex]

Simplify multiplication

[tex]10+\sqrt{-16}[/tex]

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

[tex]10 + \sqrt{-1}*\sqrt{16}[/tex]

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

[tex]10 + 4i[/tex]
