Question

if 5 2x+1 /25 =125 find the value of x

Answer 1

Hi...☺

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..

====================================

Thanks.....☺

Answer 2

Answer:

Step-by-step explanation:

5^2x+1÷25=125

5^2x+1/5^2=5^3

Now keeping the powers in equal -

2x-1-2=3

2x-1=5

2x=5-1

X =4/2=2
