Question

evaluate the (98) ^3​

Answer 1

Answer:

941192

Step-by-step explanation:

98³ can be written as (100-2)³

So, we'll use the identity -

(a-b)³= a³-b³-3a²b+3ab²

(100-2)³ = 100³ - 2³ - 3(100)²(2) + 3(100)(2)²

              = 1000000 - 8  - 60000 + 1200 

              = 941192 

Answer - 98 ³ = 941192
