Answer 2

Answer:

Step-by-step explanation: a)  (99) cube can be written as (100-1) whole power 3 so we will get (a-b) whole cube as (a cube - b cube - ( 3 . a square. b) + ( 3.a. b square ) so we will get the solution as (1000000-1-(3.10000.1) + (3.100.1)

= 970299

b)  (102) cube can be written as (100+2) whole cube = (100 cube+2 cube+( 3. 100 square . 2 ) + ( 3.100.2 square)

= 1000000+8+60000+600 = 1060608
