Answer:
10 + 4i
Step-by-step explanation:
2 sqrt (25) + sqrt (-16) =
2 * 5 + 4i
10 + 4i
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]
