I want to learn about the law of exponent
A mathematical relation such that every input has only one out.
Spiro
yes..it is a relationo of orders pairs of sets one or more input that leads to a exactly one output.

If the plane intersects the cone (either above or below) horizontally, what figure will be created?
can you not take the square root of a negative number
No because a negative times a negative is a positive. No matter what you do you can never multiply the same number by itself and end with a negative
lurverkitten
Actually you can. you get what's called an Imaginary number denoted by i which is represented on the complex plane. The reply above would be correct if we were still confined to the "real" number line.

Suppose P= {3,1,3} Q={3,21} and R= {2,2,3}.what is the intersection
can I get some pretty basic questions
In what way does set notation relate to function notation

is precalculus needed to take caculus
It depends on what you already know. Just test yourself with some precalculus questions. If you find them easy, you're good to go.

how to prroved cos⁴xsin⁴x= cos²xsin²x are equal
Don't think that you can.
Elliott
By using some imaginary no.
