Question

(99)³ solve using identities​

Answer 1

Answer:

970299

Step-by-step explanation:

(99)^3 is also equal to =(100-1)^3

Now,here identity that must be applied is

(a-b)^3 that is equal to = a^3-b^3-3ab(a-b).

Here,

A=100

B=1,

(100)^3-(1)^3-3(100×1)(100-1)

1000000-1-29700

that is equal to 970299.
