Which of the following is equivalent to -32^3/5

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

 2.2       Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

#= color(blue)(8#

Explanation:

#32 ^ ( 3/5)#

#32#can be simplified upon prime factorisation as follows:

#32 = 2 * 2 * 2 * 2 * 2 = 2^5#

#32 ^ ( 3/5) = 2 ^( 5 * 3/5)#

#=color(blue)( 2 ^3#

#= color(blue)(8#
