PROBABILITY A box contains discs numbered from 4 to 90. If one disc is drawn at random from the box, find the
probabilitythat it bears
(i) a two-digit number
(ii) a perfect square number​

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
