Question

find the value of (1/4)^3+(1/3)^3-(7/12)^3 without actually calculating the cubes​

Answer 1

Step-by-step explanation:

(1/4)³ + (1/3)³ - (7/12)³

(1/4 + 1/3)(1/16 - 1/12 + 1/9) - (7/12)³

7/12 ( -1/48 + 1/9 ) - (7/12)³

7/12 ( -1/48 + 1/9 - 49/144)

7/12 (-3 + 16 - 49 ) / 144

7/12 × -36/144

7/12 × -1/4

-7/48

Answer 2

Answer:

Value of (1/4)^3 + (1/3)^3 - (7/12)^3 = -7/48
