The correct question is
What is the value of x in the following equation (1/5)^x=5^8
Applying logarithms both members
log(1/5)^x=log(5^8)
x*log(1/5)=8*log(5)
x=8*log(5)/log(1/5)
we know that
log (1/5)----> log (1)-log (5)----> 0-log (5)-----> -log (5)
so
x=8*log(5)/-log (5)------> x=-8
the answer is
-8
Answer:

Step-by-step explanation:
A suitable common denominator is 4k^2. (This eliminates the first and last choices.)

The solution to given inequality is:
x<3
Step-by-step explanation:
We have to solve the given inequality to get the value of x
Given inequality is:

Adding 20 on both sides

Dividing both sides by 5

The solution to given inequality is:
x<3
x will be equal to all values less than 3
