Answer:

c).    14 < x < 15

d).    7 < x < 8

Step-by-step explanation:

c).   (x/3)^3 = 124

Take the cube root of both sides

x/3 = 4.986630952238646

multiply both sides by 3

x = 14.959892856715938

14 < x < 15

-----------------------------

d). (x/2 - 1)^3 = 25

Take the cube root of both sides

x/2 - 1 = 2.924017738212866

Add 1 to both sides

x/2 = 3.924017738212866

multiply both sides by 2

x = 7.848035476425732

7 < x < 8
