Answer:
d.
Step-by-step explanation:
The goal of course is to solve for x. Right now there are 2 of them, one on each side of the equals sign, and they are both in exponential positions. We have to get them out of that position. The way we do that is by taking the natural log of both sides. The power rule then says we can move the exponents down in front.
becomes, after following the power rule:
x ln(2) = (x + 1) ln(3). We will distribute on the right side to get
x ln(2) = x ln(3) + 1 ln(3). The goal is to solve for x, so we will get both of them on the same side:
x ln(2) - x ln(3) = ln(3). We can now factor out the common x on the left to get:
x(ln2 - ln3) = ln3. The rule that "undoes" that division is the quotient rule backwards. Before that was a subtraction problem it was a division, so we put it back that way and get:
. We can factor out the ln from the left to simplify a bit:
![x[ln(\frac{2}{3})]=ln(3)](https://tex.z-dn.net/?f=x%5Bln%28%5Cfrac%7B2%7D%7B3%7D%29%5D%3Dln%283%29)
. Divide both sides by ln(2/3) to get the x all alone:
On your calculator, you will find that this is approximately -2.709
There are an infinite number of them.
Here are a few:
2.1
2.2
2.3
2.3000000001
2.30000000000000006
2.5
2.00009
.
.
etc.
How to find them:
You probably never heard this before, but I'll bet
you'll remember it from now on:
<em>ANY number that you can write down on paper completely, </em><em>using digits
and a decimal point if you need it but no symbols, is a rational number.</em>
If you can write it down completely without any 'comments', then it's rational.
Answer:
This is true because negative and positive is positive that why there is a addition sign in the middle and positive 40 becomes negative
