Question

evaluate the following using identities 103 /3​

Answer 1

Step-by-step explanation:

(103)3=(100+3)3=(100)3+33+3×100×3(100+3)

                                     =1000000+27+90000+2700 =1092727

(99)3=(100−1)3=(100)3−13−3×100×1(100−1)

                                     =1000000−1−30000+300 =970299
