Changing Bases to Evaluate Logarithms In Exercise, use the change-of-base formula and a calculator to evaluate the logarithm.

Ymorist [56]

Answer:

$\frac{3}{2}$

Step-by-step explanation:

Changing Bases to Evaluate Logarithms

$log_{16}(64)$

Apply change of base formula'

$log_b(a)= \frac{log a}{log b}$

log term should be the numerator and denominator is the log base

$log_{16}(64)$

$log_{16}(a)= \frac{log 64}{log 16}$

64 is 4^3 and 16 is 4^2

$log_{16}(a)= \frac{log 4^3}{log 4^2}$

Move the exponent before log

$\frac{3log 4}{2log 4}$

top and bottom has same log so cancel it out

$\frac{3}{2}$

M 2 = 2x°, m 3 = 5x°, m 1 =<br><br> 2x + 5x<br> 5x - 2x<br> 180 - 5x<br> 180 - 7x

MaRussiya [10]

We know: the sum of measures of triangle angles is 180°.

Therefore we have the equation

$m\angle1+m\angle2+m\angle3=180^o\to m\angle1=180^o-m\angle2-m\angle3$

Substitute $m\angle2=2x,\ m\angle3=5x$ :

$m\angle1=180-2x-5x=180-7x$

<h3>Answer: 180 - 7x</h3>
