Show how to use the identity below to calculate the sum of the cubes of your numbers without using a calculator.

a3 +b3 =(a+b)(a2 −ab + b2)

CHOOSE ONE set, A, B, or C to use for the following:

A) a=9 and b=12

B) a=10 and b=14

C) a=11 and b=13

Rewritten as the sum of cubes:



Calculate the sum of the cubes without using a calculator:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
