Question

If x3= 27 and y3 =125, what is the value of y-x

Answer 1

32 2/3

(32.6 repeating)

Explanation:

29/3 is 9 (just make it not 3 Xs,) so x=9

125/3 is 41 2/3 so y= 41 2/3

41 2/3 - 9 = 32 2/3

Answer 2

2

Explanation:

x^3 = 27

x^3 = 3^3

■ x = 3

y^3 = 125

y^3 = 5^3

■ y =5

■ y- x = 5-3 = 2
