Question

Simplify the given expression.

square root of negative 54 end root plus square root of negative 96

Answer 1

mathematical one..

Answer 2

\[\sqrt{-54} + \sqrt{-96}\]

Answer 3

i*sqrt(54) + i*sqrt(96)
= i*9 sqrt(6) + 4i*sqrt(6)
=13i sqrt(6)

Answer 4

\[\left(\sqrt{-54}+\sqrt{-96}\right)^2=\sqrt{-294}=7 i \sqrt{6} \]

Answer 5

\[5i \sqrt{6}\]
\[-5\sqrt{6}\]
\[-7\sqrt{6}\]
\[7i \sqrt{6}\]

Answer 6

what does the i mean?

Answer 7

@robtobey - i didnt understand..

Answer 8

why did you "square" it???

Answer 9

i stand for imaginary num i=-1

Answer 10

i=sqrt(-1)

Answer 11

Square the problem expression -> -294
Square root of -294 = 7 i radical 6
i is the imaginary number equivalent to radical 1.

Answer 12

good way @rob

Answer 13

i is an imaginary num equals to /sqrt{-1}

Answer 14

Mistake, "to radical -1.' is what was intended.

Answer 15

why you took square of whole ?

Answer 16

makes the sum easier @deadman340 he did it in less no. of steps hence consuming less time

Answer 17

so by taking square it will not effect the anss?
