Answer:
(6^4 x 2^-9)
Step-by-step explanation:
The distance around the bulletin board would be 20 feet, because you multiply 6ft 2x and 4ft 2x.
Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large (100000000000) or small (0.00000000001) to be written in a conventional manner.
The use of this notation is based on powers of 104
Example:
Big numbers:

Small numbers:

However, in areas such as physics and chemistry, scientific notation is important to make approximations such as:
mass of a proton
mass of an electron and others.
1meter=100centimeter
1centimeter=1/100meter
so cm times 1/100=meters
43 times 1/100=43/100meters aka 0.43 meters
43/100 or 0.43 meters
