When you multiply (2.2500x10^3) x (3.00 x10^5) =675,000,000 report this answer to decimal using scientific notation

Explanation:

(2.2500x10^3) x (3.00 x10^5)

First add the power values since all are to power 10 hence this will be 3+5=8

Then multiply the digit intergers ie 2.25*3=6.75

Therefore, in scientific notation this will be represented as

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
