Question

find the value of (28)^3-(78)^3+(50)^3

Answer 1

Hello Dear!!!

Here's your answer....

(28)^3-(78)^3+(50)^3

It is in the form of (a)^3 + (b)^3 + (c)^3

if a+b+c = 0....then (a)^3 + (b)^3 + (c)^3 = 3abc

Here,

a is 28

b is -78

c is 50

a+b+c = 0

28-78+50 = 0

then,

(28)^3-(78)^3+(50)^3 = 3 * 28 * (-78) * 50

(28)^3-(78)^3+(50)^3 =  -32760

-32760 is the answer.....
