Question

Which polynomial identity will prove that 64 + 27 = 91

Answer 1

The sums of cubes will be able to prove that 64 + 27 = 91

Answer 2

Addition of the two cubic numbers gives the required result.

Explanation:

We have given the equation which is:

64 + 27 =91

The numbers 64 and 27 on left hand side of equation are the cubes of 4 and 3 respectively.

We know that when these numbers are added gives us 91

Hence, in polynomial expression it is

`a^3+b^3=c`

Hence, addition of the two cubic numbers gives the required result.
