You mean b^x/b^y=b^(x−y) parentheses matter
2^(2t-1) ⋅ 5^(t-1)
= 2^2t / 2^1 * 5^t /5^1
= 4^t/2 * 5^t/5
= 20^t / 10
All of the following expressions are equal to 1/10⋅20^t. However, only one has been rearranged by applying the exponent property that states b^x/b^y=b^x−y.
a)(1/10) ⋅ 5^t ⋅ 4^t
b)(1/10) ⋅ 10^t ⋅ 2^t
c) 2^(2t-1) ⋅ 5^(t-1)
d) (1/10) ⋅ (2^2t) ⋅ (5^t)

but 4^t * 5^t = 20^t does not illustrate the named property.
It illustrates a^t * b^t = (ab)^t
There have been several of these posts, and almost all of them have been very poorly presented.
