HW 4.2 Q7

$y = \log_{11}121$

$11^y=121$

$\log_{11}x = 121$

$11^y=11^2$

$y=2$

HW 4.2 Q10

$\log_{17}\frac{1}{\sqrt{17}}$

$=\log_{17}17^{-\frac{1}{2}}$

$x=-(1/2)$

HW 4.2 Q11

$y = \log_71$

$7^y = 1$

$1 = 7^0$

$7^y = 7^0$

$y=0$

HW 4.2 Q14

$\log\frac{1}{10}$

$10^y = \frac{1}{10}$

$10y = 10^{-1}$

$y=-1$

HW 4.2 Q15

$\ln e^4\\=\log_e e^4\\=4$
