Question

I need help solving this problem. √-225 + √-49

Answer 1

15i +7i=22i

Answer 2

\[\sqrt{-225} = \sqrt{-1} * \sqrt{225}\]
= 25i

Look at it that way

Answer 3

as roots can't be defined for negative numbers, they are "imaginary" and the imaginary number is "-i"

Answer 4

*15i

Answer 5

yeah

Answer 6

dont forget to ads the 7i you got from sq root of -49! to get the total of 22i

Answer 7

lol...the answer is 15i+7i

Answer 8

Or \[\sqrt{-484}\]

Answer 9

Krb686. Please show how \[\sqrt{-225}+\sqrt{-49}=\sqrt{-484}\]??? Enquiring minds want to know!

Answer 10

Because 15i + 7i = 22i
\[i = \sqrt{-1}\]
\[22*\sqrt{-1}\]
\[\sqrt{22^{2}*-1}\]

Answer 11

Thanks, enquiring mind now happy lol.
