the size of a certain cell is 2.5 x 10^-9m. another cell is 1.5x10^3 times larger. how large is the larger cell in scientific notation?

Answer 1

To find the size of the larger cell in scientific notation, we multiply the size of the smaller cell by the given factor of 1.5x10^3.

Size of the larger cell = (2.5 x 10^-9 m) x (1.5 x 10^3)
= 2.5 x 1.5 x 10^-9 x 10^3
= 3.75 x 10^-6 x 10^3
= 3.75 x (10^-6 x 10^3)
= 3.75 x 10^-6+3
= 3.75 x 10^-3

Therefore, the larger cell is 3.75 x 10^-3 m in scientific notation.
