Answer:
D. 4
Step-by-step explanation:
The logarithm of 10 to base 10 is 1
<h3>How to determine the logarithm?</h3>
The given parameters are:
Base = 10
Number = 10
So, the expression is:

As a general rule;

The above means that;
When the base and the number are the same, the logarithm is 1
So, we have:

Hence, the logarithmic value is 1

Answer:
X=-1
Step-by-step explanation:
(X-5)1/2+5=2
(X-5)1/2=2-5
(X-5)1/2=-3
(X-5)=-3 *2
X-5=-6
X=-1
It’s B because they both equal each other I would explain more but I’m in class but the answer is definitely B
First, square both sides. This will cancel out the radical.

(a^2 = b + 6)
Then subtract 6 from both sides
b = a^2 - 6
