Question

use suitable identity and evaluate (103)3

Answer 1

Heya!!

--------------------------

I think question is (103)^3 *

= (100+3)^3

= (100)^3 + (3)^3 + 3(100)(3) (100+3)

= 1000000 + 27 + 900(103)

= 1,092,727

Hope it helps uh :)

Answer 2

Heya ✋

$(103) ^{3} \\ \\ = (100 + 3) ^{3} \\ \\ we \: apply \: this \: identity \: here \\ \\ (a + b) ^{3} = a ^{3} + b ^{3} + 3ab(a + b) \\ \\ = (100) ^{3} + (3) ^{3} + 3 \times 100 \times 3(100 + 3) \\ \\ = 1000000 + 27 + 900(103) \\ \\ = 1000027 + 92700 \\ \\ = 1092727$



Thanks :))))))
