Question

(27/8) power 2/3 - (1/4) power-2 +5 power 0.. simplify it

Answer 1

Hi ,

( 27/8 )^2/3 - ( 1/4 )^-2 + 5^0

= ( 3³/2³ )^2/3 - ( 1/2² )^-2 + 1

[ Since a^0 = 1 ]

= [ ( 3/2 )³ ]^2/3- [ ( 1/2 )² ]^-2 + 1

= ( 3/2 )^3×2/3 - ( 1/2 )^-2/2 + 1

= ( 3/2 )² - ( 1/2 )^-1 + 1

= 9/4 - ( 2/1 ) + 1

= 9/4 - 2 + 1

= 9/4 - 1

= ( 9 - 4 )/4

= 5/4

I hope this helps you.
