a) (-3)² : √9 = = 9 : 3 = 3
b)2 * ³√8 + 3 * √4 = 2 * 2 + 3 * 2 = 4 + 6 = 10
c) 1/5 * √25 - 3 : ³√27 = 1/5 * 5 - 3 : 3 = 1 - 1 = 0
d) √1/4 + (-1/2)² = 1/2 + 1/4 = 3/4
e) ³√1/64 + √16 * ¾ ² = 1/4 + 4 * 9/16= 1/4 + 3/4 = 4/4 = 1
f) √16 : √4 : (-2)³ * (-1/4) 1 = 4 : 2 : (-8) * (-1/4) = (-2/8) * (-1/4) = 2/32 = 1/16
g) ³√ 8² - 3² + (-3)² = 4 - 9 + 9 = 4
h) √(-4)² - √49 = 4 - 7 = -3
