Find the derivative of x^(2)e^(1/x)

How would you find the derivative of x^(2)*e^(1/x)? Specifically, I get stuck when it comes to the derivative of e^(1/x)... Apparently the answer is (2x-1)*e^(1/x)... Please show working/explain?-f(x)

Math: x^2 + bx + c please help.

Pleaseeeee help, I dont understand it. It says factor each trinomial. ^means: to the power of. 1. X^2 + 10x + 24. 2. Y^2 + 12y + 20. 3. A^2 + 15a + 54. 4. H^2 + 18h + 45. 5. X^2 + 16x + 48. 6. C^2 +

Y= -x+1 2x - y = 5 Solve the system of equations using the substitution method

y= -x+12x - y = 5Solve the system of equations using the substitution method-since y=-x+1, you plug -x+1 into the second equation as y. so 2x-(-x+1) =5. then you have 2x+x-1=5 which becomes 3x-1=5. mo

Sin^2x + cos^2x/tanx=cotx

step by step help please-Sin^2x + cos^2x = 1 therefore Lhs = 1/tanx which is cotx

What is the Integral of ln3xdx

What is the integral of ln3xdx?? I think integration by parts needs to be used but not sure how to break that-Use integration by part u = ln3x du = 1/x v = 1 dv = x xln3x - INT(x/x) xln3x - x + c

Please help me solve this

there is 3 problems that i need to help solve. 1) x^3 = 4x^2 + 77x 2) x^2 - 13x = -30 3) 7x^2 -5x = 14x - 10-1) x³ = 4x² + 77x. Collect everything on one side: x³ - 4x² - 77x = 0. Factor out x: x(

Why does 1 mm^2 = 1/100,000 m^2? Doesn't 1 m^2 = 1/100m x 1/100m, or 1/10,000 m^2

My question is 4,000,000 mm^2 = ? m^2. I know the answer is 4. However, when I solve it...I get 400, since I believe 1 mm^2 = 1/100m x 1/100m which equals 1/10,000 m^2. Why does 1 mm^2 = 1/100,000
