Question

(11 sq rt of -8)(-13 sq rt -5)

Answer 1

(11sqrt(-8))(-13sqrt(-5))

((11*2isqrt(2)))(-13sqrt(-5))

((22i)sqrt(2))(-13sqrt(-5))

(22isqrt(2))(-13sqrt(-5))

(22isqrt(2))((-13*isqrt(5)))

(22isqrt(2))((-13i)sqrt(5))

(22isqrt(2))(-13isqrt(5))

286sqrt(2)sqrt(5)

Answer 2

Close there Luis. But there is no \[i ^{2}\] in the answer.

Should be \[286\sqrt{10}\]

Answer 3

\[i ^{2}= -1\]

So (-13)*2*11*(-1)= 286
