Question

How is each measurement represented using scientific notation?0.000000655 mL = 6.55 × 10-7 mL 6.55 × 109 mL 655 × 106 mL

Answer 1

Answer : The given number in scientific notation will be, $6.55\times 10^{-7}ml$

Explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example :

90000 is written as $9.0\times 10^4$

999.9 is written as $9.999\times 10^{-2}$

As we are given that the number is, 0.000000655 ml

This number is written in scientific notation as :

$6.55\times 10^{-7}ml$

Hence, the given number in scientific notation will be, $6.55\times 10^{-7}ml$

Answer 2

The answer is: 6.55 x 10^ -7
