give me an example of a problem so that I can practice answering
dont forget the cube in each variable ;)

of she solves that, well ... then she has a lot of computational force under her command ....

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.

Is a rule that assigns to each element X in a set A exactly one element, called F(x), in a set B.

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.
Spiro
the solution doesn't seem right for this problem

how to prroved cos⁴xsin⁴x= cos²xsin²x are equal
Don't think that you can.
Elliott
By using some imaginary no.
Tanmay
how do you provided cos⁴xsin⁴x = cos²xsin²x are equal
What are the question marks for?
Elliott
Someone should please solve it for me
Add 2over ×+3 +y4 over 5
simplify (×+a)with square root of two ×root 2 all over a
multiply 1over ×y{(×y)(×+y)} over ×y
For the first question, I got (3y2)/15
Second one, I got Root 2
Third one, I got 1/(y to the fourth power)
I dont if it's right cause I can barely understand the question.
Is under distribute property, inverse function, algebra and addition and multiplication function; so is a combined question
