Answer» Thanks Question 1. 102x3=306 2. 140x96=13440 3. (x+4)(x+10) =x+x of 4+10 = 2x of 14 = 28x answer. Let us rewrite\xa0(102)3\xa0as\xa0(100+2)3Now using the identity\xa0(a+b)3=a3+b3+3ab(a+b), we get(100+2)3=1003+23+[(3×100×2)(100+2)]=1000000+8+(600×102)=1000000+8+61200=1061208Hence,\xa0(102)3=1061208 |
