.1 or 10%

Step-by-step explanation:

E= Exam

P=Paper

E= .71

P= .45

E∩P=.26

A.) E∪P=?

E∪P= E+P-E∩P

.71+.45-.26= .9

B.) E'∩P' = (E∪P)'

(E∪P)' = 1-.9 = .1

How to express exponential equation, 3^c = 27 , as a logarithmic equation

trasher [3.6K]

If you consider the logarithm base 3 of both sides, you have

$\log_3(3^c) = \log_3(27)$

You can use a rule of logarithms that allow you to turn exponents into multiplicative factors:

$\log_a(b^c) = c\log_a(b)$

So the equation becomes

$c\log_3(3)=\log_3(27)$

Now, by definition, you have

$\log_a(b)=c \iff a^c=b$

So, you have

$\log_3(3)=x \iff 3^x=3 \iff x = 1,\quad \log_3(27)=y \iff 3^y=27\iff y=3$

So, the equation becomes

$1\cdot c = 3 \iff c=3$
