How do you determine the base when solving for x by converting to a log?

worty [1.4K]

$$x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}$

Solution:

Given expression:

$$(1.0125)^{4 x}=\frac{3}{2}$

To solve the expression:

$$(1.0125)^{4 x}=\frac{3}{2}$

<em>If f(x) = g(x) then ln(f(x)) = ln(g(x)).</em>

Using the above condition, we can write

$$\ln \left(1.0125^{4 x}\right)=\ln \left(\frac{3}{2}\right)$

Apply log rule: $\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)$

$$4 x \ln (1.0125)=\ln \left(\frac{3}{2}\right)$

Divide both side of the equation by $4 \ln (1.0125)$ .

$$\frac{4 x \ln (1.0125)}{4 \ln (1.0125)}=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}$

$$x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}$

The answer is $x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}$ .

Approximately how much larger is the population of Pennsylvania than the population of Ohio? Pennsylvania's population is 12,604

nadya68 [22]

Answer= 1 million

For an approximation we don't use exact numbers. Seeing as Pennsylvania has a population of around 12.6 million and Ohio has a population near 11.5 million, there is about a difference of 1 million when comparing the populations.
