Step-by-step explanation:
Here is your answer....☺
====================================
{5}^{2x + 1} \div 25 = 125 \\ = > {5}^{2x + 1} \div {5}^{2} = 125 \\ = > {5}^{2x + 1 - 2} = {5}^{3}
Now, but equating the power we have,
=> 2x +1 - 2 = 3
=> 2x - 1 = 3
=> 2x = 3+1
=> 2x = 4
=> x = 4/2
=> x = 2
Hence, the value of x = 2..
