Answer:

Step-by-step explanation:

Given that Amir is sorting his stamp collection. He has made a chart of what countries the stamps are from

He got results as

France 1/3  

Morocco 5/12  

Spain 1/6

To find out what fraction of Amir's stamps are from France, Morocco, or Spain, we have to simply add the three as there is common element between any two pairs

Hence answer is

\frac{1}{3} +\frac{5}{12} +\frac{1}{6}\\ =\frac{11}{12}

Answer:

Leaving it in Radical form

Step-by-step explanation:

You cannot write out the entire real decimal without having to round because it is a never ending decimal like pi. If you are looking to type it into a calculator then radical form is best. However, if you are looking to add it to a decimal then converting to a decimal to show your work would be better than showing a radical.

Given the exponential equation 3* = 243, what is the logarithmic form of the equation in base 10? (5 points)
Andrej [43]

Answer:

x = \frac{log\ 243}{log\ 3}

Step-by-step explanation:

Given

3^x = 243

Required

Express as a logarithm

3^x = 243

Take log of both sides

log\ 3^x = log\ 243

Apply the following law of logarithm

log\ a^b = b\ log\ a

So, the expression becomes:

log\ 3^x = log\ 243

x\ log\ 3 = log\ 243

Divide both sides by log 3

\frac{x\ log\ 3}{log\ 3} = \frac{log\ 243}{log\ 3}

x = \frac{log\ 243}{log\ 3}

Hence, the expression in base 10 is:

x = \frac{log\ 243}{log\ 3} or x = \frac{log_{10}\ 243}{log_{10}\ 3}
