Question

Write the expansion form: $(\frac{p}{q})^{4}$

Answer 1

Solution :

*************************************
We know the Exponential laws :

i ) ( a/b )ⁿ = aⁿ/bⁿ

ii ) aⁿ = a * a * a * ......n times

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

Expansion of ( p/q )⁴


Method 1 :

( p/q )⁴

= p⁴/q⁴

= ( p * p * p * p )/( q * q * q * q )

Method 2 :

( p/q )⁴ = ( p/q )*( p/q ) * ( p/q )* ( p/q )

= ( p * p * p * p )/( q * q * q * q )
