Rewrite 34 = 81 in logarithmic form.

Anna35 [415]

Answer:

$log_3(81) = 4$

Step-by-step explanation:

Given

$3^4 = 81$

Required

Rewrite in logarithmic form

We start by taking log of both sides

$3^4 = 81$

$log3^4 = log81$

From laws of logarithm;

$loga^b = b\log(a)$

So; $log3^4 = log81$ becomes

$4log3 = log81$

Divide both sided by log3

$\frac{4log3}{log3} = \frac{log81}{log3}$

$4 = \frac{log81}{log3}$

From laws of logarithm;

$\frac{loga}{logb} = log{_b}(a)$

So;

$4 = \frac{log81}{log3}$ becomes

$4 = log_3(81)$

$log_3(81) = 4$

Hence, $3^4 = 81$ in logarithm form is $log_3(81) = 4$

Calvin wants to buy a car alarm that has a full price of $325, plus a 12% sales tax. Which is the better offer, a 35%-off sale o

tester [92]

First calculate the total price of the car alarm
P = 325 + 0.12(325)
P = $ 364 is the total prize of the car alarm

then calculate the discounted price
35%-off sale
P = 364( 1 - 0.35)
P = 364(0.65)
P = $ 236.6

$ 100 coupon
P = 364 - 100
P = $ 264
so it is better to have the 35%-off sale
so the answer is A
