Which expression is equivalent to √ -80?

Explanation:

Factor -80 in such a way where we pull out -1 and we also factor out the largest perfect square possible. In this case, it would be 16 because 80 = 16*5. So this means -80 = -1*16*5 which leads to...

sqrt(-80) = sqrt(-1*16*5)

sqrt(-80) = sqrt(-1)*sqrt(16)*sqrt(5)

sqrt(-80) = i*4*sqrt(5)

sqrt(-80) = 4i*sqrt(5)

sqrt(-80) = 4*sqrt(5)*i

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
