You write them, one below the other, with their decimal points aligned.
line up the demials
line up the decimals together
"conjugate" That step is called "rationalizing the denominator", although it actually makes the denominator 'real', but not necessarily 'rational'.
factor
Get rid of the denominator.
Write them one above the other with the decimal points aligned.
STEP 1:Take out the points and multiply as normal. STEP 2:After multiplying,count the numbers that are after the decimal points. STEP 3:Then look at your answer and put in your decimal places from the right to the left.
AA is not rational.
to know where to step and how long
If the first step is writing down the numbers, the second step is finding their prime factorizations.
The first step is to sort the numbers from highest to lowest. The range is then the difference between the first and last numbers, or the highest and lowest.
Write the numbers in a column so that all the decimal points are one below the other. Put a decimal point in the answers underneath the coumn of decimal points. Then add the numbers ignoring the decimal points.
