For students who wish to study for the scientific notation test, there are some resources listed below.

Scientific notation is a product of a number between 1 and 10 and a power of 10.

Try these questions.

Change a number to scientific notation

Note that 10^2 means

ten to the exponent 2, which is the same as ten squared.

Similarly, 3x10^4 means 3 times ten to the exponent 4, or 3 times 10,000

843 000 000 =
843 000 =

Conversion questions

Given that:

1 foot= 12"
3'= 1 yard
1"=2.54 cm
100cm = 1m

Convert the following to cm:

17"
31"
1' 3"
523 yards, 2' 4"
394.76 m
12,435 km
4.3 x 10^{^-10} m
