In mathematics, the notation "y3" typically represents the cube of the variable "y," which is equivalent to y * y * y. This is a shorthand way of denoting the result of multiplying y by itself three times. The cube of a number is the number raised to the power of 3.
Well, darling, the square root of x to the fourth power is simply x squared. It's like asking how many slices of cheesecake you can fit in your mouth at once - the answer is two, unless you're feeling extra ambitious. Just remember, math may be complex, but dessert is always a simple pleasure.
e2x=ex^2 basically means that x2=2x, in which case x2-2x=0, x = 0, 2. I don't think that's what the question meant. It could mean: e2x=(ex)2 . Which comes from one of the rules of exponents. Basically, look at it this way: Take the natural log of both sides: ln e2x= ln(ex)2 From rules of logs: (2x) ln e = (2) ln ex 2x ln e = (2) (x) ln e 2x = (2)(x)
