Final Exams
Tommorow. I got some questions lol, most of them I know I can find in my note, too bad they are just too damn messy. I hope you guys can help me out here.
#1: How do you find out square roots? I totally forgot... any and all methods would be appreciated.
#2: How do you find the 3 types of percentages again??
#3: What's Scientific Notation? In the messy notes that I have been able to find, I see a 2x10( [10]by the power of 5) Then I wrote 3x10[10 squared] ?? Or did I just copy the stuff wrong.
Thx, get back to me soon!! It's tommrow!!

The square root of a number, let's say X, where another number, let's say Y, has the following property. YxY=X
Example: because
Not all numbers have integer square roots. In fact, most do not. There is also a bit of algebra associated with square roots. But that is the jist of it.
I'm not familiar with three types of percentages. Maybe you mean decimal, fraction, and percentage representations. Is this maybe what you're talking about?
The first number must be between 1 and 10. From there, if the power that 10 is raised to is positive, move the decimal place to the left that many times. If it is negative, most the decimal place that many times to the right.

No, like for the square root tell me how. I know what it is. Like the square root of 100 is 10. 10x10=100. But I need to know the method. Like, what's the square root of 212. ???

The has no exact decimal form. It's about 14.56. You can simplify the answer, but to find the decimal representation I think a calculator is the best way to go.

Too late. I already had my test <_<
