Question

2p+1/p=4 to p3+1/8p3=?

Answer 1

Hi ,

There is an error in the question.

It may like this ,

p + 1/2p = 4 ---( 1 )

*********************
We know the algebraic identity

x³ + y³ = ( x + y )³ - 3xy( x + y )

******************************

Now ,

p³ + ( 1/2p )³

= p³ + 1/8p³

= ( p + 1/2p )³ - 3 × p × 1/2p( p + 1/2p )

= 4³ - 3 × 1/2 × 4

= 64 - 6

= 58

I hope this helps you.
