b)³√1000-100

c)4√¹/¹²¹

e) 2³√125-3

h) √16+³√125

i) √169+√36-√49

j) ³√1000*√9

k) √900 : ³√27+49

l) 3√36+5³√-64

Answer 1

A) √81 + 5 = 9+5 = 14
b) ∛1000 - 100 = 10 - 100 = -90
c) 4 √1/121 = 4 / 11
d) ∛-27 / 18 = (-3)/18 = -1/6
e) 2 ∛125 - 3 = 2 * 5 - 3 = 7
f) 6 / √144  + 1 = 6/12 + 1= 1 1/2
g) 3 ∛-8∛∛ / 4 - 5 = 3 * (-2) / 4 - 5 = -6/4 - 5 = -3/2 - 5 = -6,5
h) √16 + ∛125 = 4 + 5 = 9
i) √169 + √36 - √49 = 13 + 6 - 7 = 12
j) ∛1000 * √9 = 10 * 3 = 30
k) √900 / ∛27 + √49 = 30 / 3 + 7 = 17
l) 3 √36 + 5 ∛-64 = 3 * 6 + 5 * (-4) = 18 + (-20) = -2
