Question

the size of a cell is typically found by capturing an image under a microscope then using software to measure its diameter. two cells are measured using this method: cell g: 7.77 × 10^(-3) centimeters cell h: 9.3 × 10^(-4) centimeters how much larger is the diameter of cell g than the diameter of cell h? express your answer using either standard notation or scientific notation.

Explanation:

Step1: Rewrite the numbers in the same power - of - 10 form

We rewrite $9.3\times10^{-4}$ as $0.93\times 10^{-3}$.

Step2: Subtract the two numbers

We subtract the diameter of cell H from the diameter of cell G. $(7.77\times 10^{-3})-(0.93\times 10^{-3})=(7.77 - 0.93)\times10^{-3}$.
$7.77-0.93 = 6.84$, so the result is $6.84\times 10^{-3}$ centimeters.

Answer:

$6.84\times 10^{-3}$ centimeters
