Use this information to evaluate the following. Hint: do not try to solve for the value of a. loga 2 = 0.32
loga 3 = 0.50
loga 5 = 0.73

a. loga 15 =
b. loga (5/3) =
c. loga(8a7)

a. 1.23

b. 0.23

c. 7.96

Step-by-step explanation:

Use laws of logarithms:

log(a*b) = log(a) + log(b)

log(a/b) = log(a) - log(b)

log(a^b) = b*log(a)

log_k(k) = 1

a. log_a(15) = log_a(3*5) = log_a(3) + log_a(5) = 0.50 + 0.73 = 1.23

b. log_a(5/3) = log_a(5) - log_a(3) = 0.73 - 0.50 = 0.23

c. log_a(8*a^7) = log_a(8) + log_a(a^7) = log_a(2^3) + log_a(a^7)

  = 3log_a(2) + 7log_a(a) = 3(0.32) + 7(1) = 7.96

step-by-step explanation:

the option best identifies the textual evidence that supports this conclusion is c.) when an argument is over, how many weighty reasons does a man recollect which his heat and violence made him utterly forget? in order to recognize textual evidence is to identify the topic sentence where the author states the main idea. textual evidence is what supports the topic sentence or main idea of a passage.
