Answer:

Step-by-step explanation:
You know how subtraction is the <em>opposite of addition </em>and division is the <em>opposite of multiplication</em>? A logarithm is the <em>opposite of an exponent</em>. You know how you can rewrite the equation 3 + 2 = 5 as 5 - 3 = 2, or the equation 3 × 2 = 6 as 6 ÷ 3 = 2? This is really useful when one of those numbers on the left is unknown. 3 + _ = 8 can be rewritten as 8 - 3 = _, 4 × _ = 12 can be rewritten as 12 ÷ 4 = _. We get all our knowns on one side and our unknown by itself on the other, and the rest is computation.
We know that
; as a logarithm, the <em>exponent</em> gets moved to its own side of the equation, and we write the equation like this:
, which you read as "the logarithm base 3 of 9 is 2." You could also read it as "the power you need to raise 3 to to get 9 is 2."
One historical quirk: because we use the decimal system, it's assumed that an expression like
uses <em>base 10</em>, and you'd interpret it as "What power do I raise 10 to to get 1000?"
The expression
means "the power you need to raise 10 to to get 100 is x," or, rearranging: "10 to the x is equal to 100," which in symbols is
.
(If we wanted to, we could also solve this:
, so
)
The answer is 5 hoped that helped and good luck (:
Answer:
2 and 3
Step-by-step explanation:
6 = 2 × 3, so if a number is divisible by 6, it is also divisible by 2 and 3.
Answer: Please mark me brainliest, it will really help me just as this answer really helps you.
Description: Divide by two
Next three terms: 1/8, 1/16, 1/32
Explanation:
<em>How to get next term?</em>
Divide the number before by two to get the next term.
<em>How do you get the pattern?</em>
I observed a pattern that each next number was divided by two.
Answer:
x=4
Step-by-step explanation:
ABCD is a rectangle, so AD and BC are parallel. Thus, The angle complementary to 6x+19 is 47.
6x+19+47=90
6x+66=90
6x=24
x=4
