Answer:

\log_5 92=2.809

\log_3 2.809=0.940            

Step-by-step explanation:

Given : Expression \log_5 92

To find : Use the Change of Base Formula to evaluate the expression also  convert the expression to a logarithm in base 3?

Solution :  

Applying the change of Base Formula,

i.e. \log_b x=\frac{log_a x}{\log_a b}

We get,

\log_5 92=\frac{\log 92}{\log 5}

\log_5 92=\frac{1.963}{0.698}

\log_5 92=2.809

So, The expression is \log_5 92=2.809

Now, converting the expression to a logarithm in base 3.

Taking log base 3 in 2.809,

\log_3 2.809=\frac{log 2.809}{\log 3}

\log_3 2.809=\frac{0.448}{0.477}

\log_3 2.809=0.940

Therefore, The solution is \log_3 2.809=0.940

Change of base is
log_a(b)= \frac{log_c(b)}{log_c(a)}
change base to 3
log_5(92)= \frac{log_3(92)}{log_3(5)}
why would you want base 3? base 10 is on most calculators
anyway, the value would be 2.809555

The largest number which divides 60 and 75, leaving remainders 8 and 10 respectively is? Please I need an answer with a full exp
Assoli18 [71]

Answer:

The largest number is 13

Step-by-step explanation:

Here, we want to find the largest number which divides 60 and 75 to leave remainders 8 and 10 respectively

What this means is that we are looking for numbers such that when we divide 60 by it, we get remainder 8 and when we divide 75 by it, we get remainder 10

For 60;

The number is 13 for 60

This is because, since we are looking at leaving remainder 8, that means the actual figure we are looking at is 60-8 = 52

13 is actually the biggest factor of 52 in this case

For 75;

we are looking at remainder 10; take this away from 75, that will be 75-10 = 65

Also the factor here is 13 because 13 * 5 = 65 and we are 10 units away from 75
