# How do you write 0.000000235 in scientific notation?

Nov 8, 2015

$2.35 \cdot {10}^{-} 7$

#### Explanation:

To get our answer, first know that when you write a number in scientific notation, the number that is being multiplied by ${10}^{x}$ must be between 1 and 10. Next, let's move the decimal point to a point where if will agree with the rule. If you move over the decimal point 7 spots to the right, you will get 2.35. Since we moved 7 spots to the RIGHT, this means that the exponent will be negative (which is completely normal in context of scientific notation). Using the number we got (2.35) and the exponent of -7, we can safely say that the answer is $2.35 \cdot {10}^{-} 7$.

Hope this helps!

$0.000000235 = 2.35 \times {10}^{- 7}$

#### Explanation:

$0.000000235$

Move the decimal to the right until it is after the $2$, so that there is one nonzero digit in front of the decimal. Since the decimal was moved to the right seven places, the exponent will be $- 7$.

$2.35 \times {10}^{- 7}$
