Question

How do you write `270 000 000` in scientific form?

Answer 1

`2.7 x 10^8`

Explanation:

In scientific notation the number is written with one digit to the left of the decimal and the remaining digits written to the left of the decimal. The digits are then multiplied by a power of ten.

In this case the decimal is written to the right of 2 and to the left of 7.

counting from the decimal point to the right of 2 there are 8 places.
This results in 10 to the eight power. or `10^8`

so 270000000 = `2.7 xx 10^8` in scientific notation.
