Question

If 5^4x *5^-2x=125*5^ x , fund the value of x​

Answer 1

Heya mate

Here is your answer

5^4x * 5^-2x = 125 * 5^x

5^4x * 5^-2x = 5^3 * 5^x

bases are equal , so powers must be equal .

4x - 2x = 3 + x

2x = 3 + x

2x - x = 3

x = 3

Hope this helps you .

Follow me !!!!

Answer 2

5^4x * 5^-2x = 125 * 5^x

5^4x * 5^-2x = 5^3 * 5^x

Since the bases are same, powers

will also be same..

4x - 2x = 3 + x

2x = 3 + x

2x - x = 3

x = 3
