I am asked to show that:
|-- (Ax)(A --> (B = C)) --> ((Ax)(A --> B) = (Ax)(A --> C))

Note: (Ax), the A is supposed to be upsidown.

I could solve this if the (Ax) wasn't there, but it is, and it's throwing me off. I know what it means, but what's the difference in terms of solving? Can I just pretend it's not there, and solve anyway?

find the values for the constants a and b such that
limit as x approaches o
the numerator is square root (a + bx) -square root of 3
and the denominator is x
and the function is equal to the square root of 3
so u have to find what a b are
any questions email me at watsgud1524@yahoo.com

f) As flour is poured onto a table it forms a right circular cone. The lateral surface area of this cone is described by the formula:
L=(pie)R SquarRoot R^2+H^2

where L is the lateral surface area,
R is the radius of the base of the cone
H is the height of the cone
If the height of the cone is 4 inches and the lateral surface area is 15 square inches,
find the radius of the cone. ?

In order to solve x^i ≡ a(mod m), one must find integers b and c satisfying ib - φ(m)c = 1. The solution is x ≡ a^i (mod m).

How does one prove that x ≡ a^i (mod m) is a solution to x^i ≡ a (mod m) even if the greatest common divisor of a and m is greater than 1?

You're at a cheap carnival. A sharp operator accosts you, and convinces you to try a game with cups and a pea. You agree. He shows you 5 cups upsidedown, one of them covering a pea, and asks you if you can guess which one? You choose one. He looks at you for a moment, and then decides to turn over 3 other cups, showing no pea, so that either the remaining cup has the pea, or yours does. He says you can change your mind if you want. What should you do?

Hi.
I've got some really hard homework on indices and equations, there are 3 questions that I'm particularly stuck on.. Even if you could answer one of them, it would be a great help - and please don't use logarithms:
i) 0.25 = 4^x-2
ii) 1/9 = 3^(x/2)
iii) 0.125 = (1/4)^-x

Thanks!
