Answer:
Step-by-step explanation:
Follow these steps. First let's look at the problem:
[tex]1.04=2^{\frac{1}{j}}[/tex]
Multiply each side by j/1:
[tex]1.04^{\frac{j}{1}} =2^{\frac{1}{j} *\frac{j}{1}}[/tex]
which simplifies to
[tex]1.04^j=2[/tex]
Now take the natural log of both sides:
[tex]ln(1.04)^j=ln(2)[/tex]
The power rule says that we can bring the exponent down in front of the natural log:
(j) ln(1.04) = ln(2) and then divide both sides by ln(1.04)
Do the division on your calculator to get that j = 17.7
