Concept
If the bases of two equal numbers are equal, then their powers must be same. For example, if (a)^b = (a)^c, the b and c must be equal.
Given
an expression (2/3)^6 × (9/4)^5 = (3/2)^m+2
Find
we need to find the value of m
Solution
We have
(2/3)^6 × (9/4)^5 = (3/2)^m+2
we can rewrite the equation as
(2/3)^6 × (3/2)^10 = (3/2)^m+2
after cancelling out the common terms we will be left with
(3/2)^4 = (3/2)^m+2
now since the bases on both sides are equal, the powers will be equal
4 = m+2
m = 2
Thus, the value of m is 2.
