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
