Find the value of ( 0.75 * 0.75 * 0.75 - 0.001 ) / ( 0.75 * 0.75 - 0.075 + 0.01)
(a) 0.845 (b) 1.908 (c) 2.312 (d) 0.001

• ans is option a
  (cube(0.75)-0.001)/(sqr(0.75)-0.075+0.01)=0.8459

• ans a
  (0.75*0.75*0.75-0.001)=0.75^3 -0.1^3
  0.75*0.75-0.075+0.01=0.75^2-0.1^2
  a^3-b^3=(a+b)(a^2-ab+b^2)
  so after cancellation remainning term is (a+b) i.e 0.75+0.1=0.85
  nearly to 0.845

• (0.75-0.1)(0.75×0.75+0.01+0.075)=(0.75×0.75×0.75-0.1³)
  ans is 0.75-0.1=0.74
