Question

EXPONEN TAL FORM (25)^2x1=(125)^x-3 find X

Answer 1

answer :

solution

If 5  

2x−1

=1/(125)  

x−3

, find x.

Let us simplify the given expression,

5  

2x−1

=1/(5  

3

)  

x−3

 

5  

2x−1

=1/5  

3x−9

 

5  

2x−1

=5  

3x+9

 

Now by comparing the powers, we get

2x−1=−3x+9

2x+3x=9+1

6x=10

x=10/5

=2
