Question

Three number a b c are in ratio 3:4:5 if a cube + b cube + c cube - 27 = 4069 find the value of a b in ratio

Answer 1

HERE IS UR ANSWER PLZ MARK BRAINLIEST

let a=3x

b=4x

c=5x

(3x)³+(4x)³+(5x)³-27 = 4069

27x³ + 64x³+125x³ - 27 = 4069

27x³ + 64x³+125x³ = 4069 + 27

27x³ + 64x³+125x³ = 4096

(27x + 64x 125x)³ = 4096

(a+b+c)³= 4096

solve it ....u will get value of x and put that value in the assumed number
