Question

a^6+516^6 Factorise it.

Answer 1

Answer:

Step-by-step explanation:

Rewrite A⁶+516⁶ as (A²)³+266256³

as, by using exponent rule aᵇⁿ = (aᵇ)ⁿ

A⁶= (A²)³

516⁶= (516²)³

= (A²)³ + 266256³

Now apply the identity : x³+y³= (x+y) (x²-xy+y²)

So, (A²)³ + 266256³ = (A² + 266256) ( A⁴-266256A²+ 266256²)

Hence factorised , (A² + 266256) ( A⁴-266256A²+ 266256²)
