So to work this out we need to find the 4th root of each of those and pick the one that gives an integer.

A: $\sqrt[4]{1.6*10^1^1} = 632.455...$ This is a decimal therefore not an integer.

B: $\sqrt[4]{1.6*10^1^2} =1124.682...$ Again a decimal, therefore not an integer.

C: $\sqrt[4]{1.6*10^1^3} =2000$ This is a whole number, so it is an integer.

D: $\sqrt[4]{1.6*10^1^4} =3556.558...$ Decimal, therefore not an integer

E: $\sqrt[4]{1.6*10^1^5} =6324.555...$ Again a decimal, not an integer.

The only one that gives an integer when put to the 4th root is C, therefore:

$1.6*10^1^3$ could be A^4, as the 4th root of it is an integer.

You decide to put $5000 in a savings account to save $6000 down payment on a new car. If the account has an interest rate of 7%

$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill&\$6000\\ P=\textit{original amount deposited}\dotfill &\$5000\\ r=rate\to 7\%\to \frac{7}{100}\dotfill &0.07\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{monthly, thus twelve} \end{array}\dotfill &12\\ t=years \end{cases}$

$\bf 6000=5000\left(1+\frac{0.07}{12}\right)^{12\cdot t}\implies \cfrac{6000}{5000}\approx (1.0058)^{12t}\implies \cfrac{6}{5}\approx(1.0058)^{12t} \\\\\\ \log\left( \cfrac{6}{5} \right)\approx \log[(1.0058)^{12t}]\implies \log\left( \cfrac{6}{5} \right)\approx 12t\log(1.0058) \\\\\\ \cfrac{\log\left( \frac{6}{5} \right)}{12\log(1.0058)}\approx t\implies 2.63\approx t\impliedby \textit{about 2 years, 7 months and 16 days}$
