Q. 1.4×105 bacteria are measured to be in a dirt sample that weighs 1 gram. Use scientific notation to express the number of bacteria that would be in a sample weighing 4 grams.Answer: □×10□
Multiply by 4: We know the number of bacteria in 1 gram, and we need to find out how many bacteria would be in 4 grams. Since the weight is multiplied by 4, the number of bacteria will also be multiplied by 4.
