Question

find the value of x 5^x-1 ×25 =125​

Answer 1

Answer:

x=2

Step-by-step explanation:

5^x-1 × 5^2=5^3

x-1+2=3

x+1=3

x=2

Answer 2

here given as

$5^{x-1 }$ *$25 =125$

now we can write this equation as

$5^{x-1}$ *$5^{2}$ $=5^{3}$

Now since the base term in equation is same, according to laws of exponents we can equate them as

$x-1 =2+3$

$x-1 =5$

$x=5+1$

$x=6$
