Question

1. the length of plant cell a is 8×10^(-5) meter. the length of plant cell b is 0.000004 meter. how many times greater is plant cell as length than plant cell bs length?

Explanation:

Step1: Write cell B's length in scientific - notation

$0.000004 = 4\times10^{-6}$

Step2: Calculate the ratio of cell A's length to cell B's length

$\frac{8\times 10^{-5}}{4\times 10^{-6}}=\frac{8}{4}\times\frac{10^{-5}}{10^{-6}}$

Step3: Simplify the fraction

$\frac{8}{4}=2$, and $\frac{10^{-5}}{10^{-6}} = 10^{-5-(-6)}=10^{1}=10$. Then $2\times10 = 20$

Answer:

20
