Answer:

Step-by-step explanation:
log20 = 1.301 (when you see only "log" with no base, it is taken as a base 10)
This basically means:
(This is the log in exponential form)
Since we don't know what
is equal to, we will say
= x
So to solve for
= x, you do the same thing. (convert to exponential form)

Now you will notice that both of these equations are equal to 20.
Since 20 = 20,
we can say
= 
Another way of saying 100, is
(make the bases the same)
Now we get
(we get 2x because an exponent to the power of an exponent (
) is the same as 2 * x)
Because you have the same base, you can just ignore the 10s and focus on the exponents. So you get:
2x = 1.301
x = 0.6505
Answer:
the answer is 70.84. hope this helps
X+ y = 44
x - y = 6
—————
2x = 50
x = 25
y = 44-x = 19
When you add the decimals it’s the same as regular adding. You line up the decimals and then add all the way across and when you get to the decimal carry it down
