Question

Find the value of (103)³ ( using cubic identity ) ​

Answer 1

Answer:

(103)³ = (100 + 3)³

(a + b)³ = a³ + b³ + 3 x a² × b + 3 x a x b³

          = 100³ + 3 ³ + 3 ×100² × 3 + 3 × 100 × 3²

            = 100000 + 27 + 90000 + 2700

                 = 1092727

Answer 2

Answer:

$(100 + 3) {}^{3 } \\ = 100 {}^{3} + {3}^{3} + 3. {100}^{2} .3 + 3.100. {3}^{2} \\ =1000000 + 27 + 90000 + 2700 \\ = 1092727$
