Answer:
25 / 16
Step-by-step explanation:
( 5 / 4 )^4 / ( 5 / 4 )^2
By the formula,
( a )^m / ( a )^n = ( a )^( m - n )
=> ( 5 / 4 )^( 4 - 2 )
=> ( 5 / 4 )^2
=> ( 5 )^2 / ( 4 )^2
=> 25 / 16

(5by4)^4 × (5by4)^2
=(5by4)^6 {if the product is the same add the exponents}
=5^6 × b^6 × y^6 × 4^6
=15625 × b^6 × y^6 × 4096
=15625 b^6 y^6 4096
