Simplify 200

               8^-2/3

Solution

=  200

    8^-2/3

= 200 x 1

           8^-2/3

=  200 x 8^2/3        [Since 1/a^-n = aⁿ]

=  200 x (8^1/3)²        [Since 8^1/3 = cube root of 8 = 2]

=  200 x (2)²        

=  200 x 4

= 800       

          

Hence   200        = 800

              8^-2/3
