Letf(x)={|⌊x⌋|if x is rational,⌈x⌉2if x is irrational.Findf(3√−8)+f(−π)+f(√50)+f(92).
∛-8 = -2 which is rational
l floor ( -2) l = l -2 l = 2
-pi is irrational
(ceiling (-pi) )^2 = (-3)^2 = 9
√50 is irrationa;
( ceiling (√50) )^2 = (8)^2 = 64
9/2 is rational
l floor (9/2) l = l 4 l = 4
2 + 9 + 64 + 4 = 79
