(a + b)3 = a3 + b3 + 3ab(a +b)
(10)3 = a3 + b3 + 3*16(10)
1000 = a3 + b3 + 480
a3 + b3 = 1000 -480 = 520
a3 +b3 = ( a+ b) (a2 - ab + b2)
520 = 10(a2 - ab +b2)
a2 - ab + b2 = 520 / 10 = 52
if we see 8 + 2 = 10 , 8 * 2 = 16
a - b = 8 - 2 = 6
(8)2 + (2)2 + 16 = 64 + 16 + 4 = 64 +20 = 84 = a2 + ab + b2
therefore,a2 - ab + b2 =52
and a2 + ab + b2=84
I hoep this helps.
