Question

if 5*=1/125 find the value of x

Answer 1

Answer:

$5x = \frac{1}{125 } \\ x = \frac{1}{125 \times 5} \\ x = \frac{1}{625}$

Answer 2

Answer:⇒x=2

Step-by-step explanation:Given, 5  

3x−1

÷25=125

Since, 25=5×5=5  

2

 

And 125=5×5×5=5  

3

 

Therefore given equation can be written as,  

5  

3x−1

÷(5)  

2

=(5)  

3

 

⇒(5)  

3x−1−2

=(5)  

3

[∵a  

m

÷a  

n

=(a)  

m−n

]

⇒(5)  

3x−3

=(5)  

3

 

On comparing both sides, we get

⇒3x−3=3

⇒3x=6

⇒x=2
