Question

if x+ 1/3 = 7 till find the {(x+2)*(x+2)*(x+2)}+{(1/x+2)*(1/x+2)*(1/x+2)}​

Answer 1

given that x+1/3=7

x=7-1/3

x=20/3(main point)

then the value of

{(x+2)*(x+2)*(x+2)}+{(1/x+2)*(1/x+2)*(1/x+2)}​

(x+2)³+(1/x+2)³

(20/3+2)³+(1/20/3+2)³

(8000/27+8)+(27/8000+8)

(297+8)+(0.0003375+8)

314(approx)
