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

(I'm not sure with my answer)
Answer:
This inequality isn't correct.
Step-by-step explanation:
2x - 2 > 2x + 4
Substituting any value for x, the result will be incorrect.
Actually,
2x - 2 < 2x + 4 is correct.
2x - 2x < 4 + 2
0 < 6
<h3>Answer:</h3>
Option B: 63
<h2>Given that:</h2>
The given function is 
<h2>Explanation:</h2>
To evaluate the value of a function at given value of input, you should replace the variable given in the function with the value of input that is given, in your case it is x = 5.
For x = 5, we have

Similarly, you will be able to evaluate the value of the function for any other input given, which is assumed to be valid.
Hence option b: 63 is the correct option.
