Question

Simplify 3.1×3.1×3.1+1.1×1.1×1.1/(divided by)3.1×3.1-3.1×1.1+1.1×1.1

Answer 1

31×31×31+11×11×11×1000000÷31×31-31+11×11×11×1000000

Answer 2

Answer:

Step-by-step explanation:

3.1*3.1*3.1+1.1*1.1*1.1/3.1*3.1-3.1*1.1+1.1*1.1

let here 3.1=x and 1.1=y

=(3.1)³+(1.1)³/(3.1)²-3.1*1.1+(1.1)²

=(3.1+1.1)(3.1)²-3.1*1.1+(1.1)²/(3.1)²-3.1*1.1+(1.1)²        (x³+y³=(x+y)(x²+y²-xy)

=(3.1+1.1)

=4.2
