Question

Evaluate (104)³ give me answers plz​

Answer 1

${104}^{3} \\ = {(100 + 4)}^{3} \\ = {100}^{3} + {4}^{3} + 3 \times 100 \times 4 \times (100 + 4) \\ = 1000000 + 64 + 120 \times 104 \\ = 1000064 + 12480 \\ = 1012544$

Identity used is :

${(x + y)}^{3} = {x}^{3} + {y}^{3} + 3 \times x \times y \times (x + y)$
