Question

Evaluate (99)(99)(99) using suitable identities

Answer 1

Answer:

The Correct Answer is

970299

Step-by-step explanation:

Given,

$99 \times 99 \times 99 = 99 {}^{3} \\ = (100 - 1) {}^{3} \\ Using \: Identity \: (a-b) {}^{3} = a {}^{3} - b {}^{3} - 3xy(x - y) \\ Therefore \: (100 - 1) {}^{3} = 100 {}^{3} - 1 {}^{3} - 3(100)(1)(100 - 1) \\ = 1000000 - 1 - 300(99) \\ = 999999-29700 \\ = 997029$
