Question

If 52x+1 + 25 = 125, find the value of x.​

Answer 1

Correct question :

If 5^2x+1 ÷ 25 = 125, find the value of x.

Given :

• 5^2x+1 ÷ 25 = 125

To find :

• x

Solution :

5^2x + 1 ÷ 25 = 125

5^2x + 1/25 = 125

5^2x + 1/5² = 5³

5^2x + 1 - 2 = 5³

5^2x - 1 = 5³

2x - 1 = 3

2x = 3 + 1

x = 4/2

x = 2

=> Value of x is 2

Answer 2

Answer:

x= 2

Step-by-step explanation:

Given 5 2x+1 ÷25=125But the above equation can be written as 5 2x+1 ÷5 2 =5 [∵25=5 2and 125=5 3 ]

Given 5 2x+1 ÷25=125But the above

base −1]⇒2x=4⇒x= 2/4[∵ On dividing]⇒x=2
