​Scientific Notation

Multiple Select

Which numbers below are written in scientific notation?

(Check all that apply)

• $$3.2\times10^7$$  

• $$250\times10^2$$  

• $$10\times2^5$$  

• $$9.2\times10^{-5}$$

​​Converting a Number from Scientific Notation to Standard Form

• Converting a number from scientific notation into standard form is as easy as shifting the decimal place.

​

• ​The number of places that the decimal point is shifted is equal to the value of the exponent.

​

• ​If the exponent is positive, the decimal point is shifted to the right.

​

• ​If the exponent is negative, the decimal point is shifted to the left.
