Question

The size of a certain cell is 2.5 x 10^-9 m. Another cell is 1.5 x 10^3 times larger. How large is the larger cell in scientific notation?

A.) 4 x 10^-27m
B.) 4 x 10^-12m
C.) 3.75 x 10^6m
D. 3.75 x 10^-6m

I honestly have no idea what to do.

Answer 1

1) C. -15x^4y

2) B. -18/m^5n

3) C. 768x^11

4) A. 2.535x10^10

5) D. 3.75x10^-6m

Answer 2

The second cell is $3.75\times 10^{-6}\;meter$ in scientific notation

• Let the first cell be A.

• Let the second cell (larger) be B.

Given the following data:

• Size of A = $2.5 \times 10^{-9}$ meter.

• Size of B = $1.5 \times 10^3$ meter of A.

To calculate how large is the second cell (larger) in scientific notation:

How to solve a word problem.

In this exercise, you're required to the determine the amount of times in which the first cell is larger than the second cell (larger) while expressing the value in scientific notation

Mathematically, this is given by this expression:

$B = A \times 1.5 \times 10^3\\ \\ B=2.5 \times 10^{-9}\times 1.5 \times 10^3\\ \\ B=3.75\times 10^{-9+3}\\ \\ B=3.75\times 10^{-6}\;meter$
