How do you solve for x where e2x plus ex equals 0?

e2x + ex = 0e2x = -exe2x / ex = -1ex = -1x = ln(-1)Actually, that's just a restatement of the original problem, but that'sas far as you can go with it, because there's no such thing as the log(or the ln) of a negative number. Your equation has no solution.


Solve e to the power x equals x to the power 3 algebraically?

ex = x3 This has two solutions: x = 4.5364... and x = 1.85718... Plot the graph of each and you can see the intersections.


Why was the calculus student confused about y equals ex and the derivative of y equals ex?

Because the derivative of e^x is e^x (the original function back again). This is the only function that has this behavior.


Y' equals x plus y Explicit solution?

using Laplace transform, we have: sY(s) = Y(s) + 1/(s2) ---> (s-1)Y(s) = 1/(s2), and Y(s) = 1/[(s2)(s-1)]From the Laplace table, this is ex - x -1, which satisfies the original differential eq.derivative of [ex - x -1] = ex -1; so, ex - 1 = ex - x - 1 + xto account for initial conditions, we need to multiply the ex term by a constant CSo y = C*ex - x - 1, and y' = C*ex - 1, with the constant C, to be determined from the initial conditions.


What is the integral of e raised to x cubed?

(ex)3=e3x, so int[(ex)3dx]=int[e3xdx]=e3x/3 the integral ex^3 involves a complex function useful only to integrations such as this known as the exponential integral, or En(x). The integral is:-(1/3)x*E2/3(-x3). To solve this integral, and for more information on the exponential integral, go to http://integrals.wolfram.com/index.jsp?expr=e^(x^3)&random=false

Solve e raised to the power of x equals 6?

If you want to solve ex =6, you need to take the natural log of both sides.ln ex =ln6Now we have x=ln6 which can be left that way or approximated with a calculator.ln means natural log, in case there was any question about that.The answer is about 1.79176.


How do you solve integer math problems?

If you're adding: Ex. -3 + 15 (-3, -2, -1, 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15) = 12If you're subtraction: Ex. -17 - 20 (add the opposite, so problem really equals 17+20)= 37If you're multiplying: Ex. 5 x -10 (one negative equals negative answer. both positive or negative equals positive answer.)= -50If you're dividing: Ex. -100/10 (same rules as multiplication)= -10

Solve e to the negative x?

I am not sure what you want to "solve" here. e-x is the same as 1 / ex.
