Question

The length of a bacterial cell is about 3 x 10^−6 m, and the length of an amoeba cell is about 4.5 x 10^−4 m. How many times smaller is the bacterial cell than the amoeba cell? Write the final answer in scientific notation with the correct number of significant digits. Step by Step needed!

2 x 10^2

2 x 10^3

0.7 x 10^1

6.67 x 10^2

Answer 1

It’s 6.54^6 that’s the answer I got

Answer 2

Explanation:

Okay, so first you take 3 × 10∧-6m back to its decimal form, giving you 0.000003. Also, take 4.5×10∧-4m back to its decimal form giving you 0.00045. You then divide 0.00045 by 0.000003 giving you 6.66666 but we then take it to 6.67 × 10∧2 which is the answer.
