Question

Find (101)³ by identity

Answer 1

(101)³=(100+1)³
we know
(a+b)³=a³+b³+3a²b+3ab²
so
100³+1³+3(100)²(1)+3(100)(1)²=1030301

Answer 2

Answer:

(101)³ = (100 + 1)³

Step-by-step explanation:

We know that ,

                    (a + b)³ = a³+b³+3a²b+3ab²

So,

    (100 + 1)³ = 100³ + 1³ + 3*100²*1 + 3*100*1²

    (100 + 1)³ = 1000000 + 1 + 30000 + 300

    (100 + 1)³ = 1030301
