In math, I learn about scientific notation. In learning scientific notation, I also learning about density, powers, exponents and base.
First do you know what is scientific notation? Scientific notation is when we make very large number into smaller number, e.g. 1,000,000,000 =109. Let’s solve this problem: Our planet mass is 5,973,600,000,000,000,000,000,000 kg and of course it’s too hard to mention this number so we use scientific notation, the way we start from the last digit and hop to the previous digit and we stop right at the number before the coma them change the coma into decimal point after that we count the amount of hops so in this problem we got 24 hops and so the final result is 5.9736 x 109
Lets talk about density. Density tells us when something will float or sink in water. Everything have a density, the density of water is always 1 g/ml. To find a density of an object we need to divided it’s mass with it’s volume then we get the density. We can know the something is floating or not in water only with finding out the density. If something has a density that is less that 1 or lower that the density of water it will definitely float but if something has the density more than 1, it will sink.
And those are the things that I have learn in math about scientific notation
