The bacterial numbers from whirlpool bathtubs were not significantly different. based on the tub location (private 1.65 x 10 6cfu/ml and hotel 2.64x 10 cfu/ml, p=0.22). Normal (nonjetted) tub water. samples (1210 cfu/ml) were not significantly different from tap water samples, (p=0.99).
A simple fraction (also known as a common fraction or vulgar fraction) is a rational number written as a/b or a b {\displaystyle {\tfrac {a}{b}}} , where a and b are both integers. As with other fractions, the denominator (b) cannot be zero.
Problem 8. Express each radical in simplest form. a) = = 2. To simplify a radical, the radicand must be composed of factors ! b) = = 2a. c) = = 3b. Fractional radicand. A radical is in its simplest form when the radicand is not a fraction. Example 6. The denominator a square number.
