Step-by-step explanation:
Length is measured 21 cm correct to 2 significant figures
a. Lower bound of 21
= 20.5 < 21
= 20.5

Answer:
The value of given log function is 1 .
Step-by-step explanation:
Given as :
Logb A = 3
Logb C = 2
Logb D = 5
<u>Now from log property </u>
if , Logb x = c , then x = 
So,
Logb A = 3 , then A = 
Logb C = 2 , then C = 
Logb D = 5 , then D = 
Now, According to question

So, 
Or, 
or, 
Now, since base same So,

∴ 
<u>Now log property </u>
= 1
Hence The value of given log function is 1 . answer
Answer: 6
Step-by-step explanation: First, let's find the least common denominator between the 2 fractions, which is 4. Now let's multiply 9/2 by 2 to get the denominator of 4. Once you multiply the numerator and denominator by 2 you would get 18/4. So now the problem turns into how many 3/4 goes into 18/4. We know that 3/4 x 6 = 18/4. So the final answer is 6.
