Easton broke a cell sample into 88 batches, each weighing 3, point, 9, times, 10, to the power minus 53.9×10

Question

grams. How much did the original sample weigh? Use scientific notation to express your answer. simplfy

Answer 1

To determine the weight of the original sample, we can multiply the weight of each batch (3.9 * 10^(-5) grams) by the number of batches (88).

Weight of original sample = (3.9 * 10^(-5) grams) * 88

To simplify, we can multiply the numbers and add the exponents of 10:

Weight of original sample = (3.9 * 88) * 10^(-5)

Weight of original sample = 343.2 * 10^(-5)

To express the answer in scientific notation, we can move the decimal point one place to the left and adjust the exponent of 10 accordingly:

Weight of original sample = 34.32 * 10^(-4) grams

Therefore, the original sample weighed 34.32 * 10^(-4) grams.
