Challenge a scientist is growing bacteria in three colonies, a, b, and c. at the moment, there are 2.3 times 10 superscript 5 baseline bacteria in colony a, 1.2 times 10 superscript 5 baseline bacteria in colony b, and 6.6 times 10 superscript 5 baseline bacteria in all. express each of these numbers in standard form. then use those results to find the number of bacteria in colony c by evaluating the expression shown below .6.6 times 10 superscript 5 baseline minus left parenthesis 2.3 times 10 superscript 5 baseline plus 1.2 times 10 superscript 5 right parenthesis 2.3 times 10 superscript 5 equals nothing
