Find the given input in the row (or column) of input values. Identify the corresponding output value paired with that input value. Find the given output values in the row (or column) of output values, noting every time that output value appears. Identify the input value(s) corresponding to the given output value.
First, recognize that all the numbers can be moved around because they are being multiplied together. Next, rearrange the expression so that the whole-number coefficients are together:
Now try to simplify the square-roots to find any squares inside that can be reduced and taken out of the square-root:
