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#
