1/3  5/6 = 1/X SOLVE 1/3  5/6 = 1/X Let's remove the denominators by multiplying by 12X 12X*(1/3)  12X*(5/6) = 12X*(1/X) Clear the fractions. 4X  10X = 12 6X=12 multipy by 1 6X=12 Divide both sides by 6 6X/6 = 12/6 X = 2

What is dy/dx of y=12/12Xy^3 ???? Any idea anyone??? y=12/12Xy^3 I assume you mean... y=12/(12Xy^3) 12Xyy^4=12 12x dy/dx + 12y 4y^3 dy/dx=0 dy/dx (12x 4y^3)=12y solve for dy/dx

Derivatives
What is the fourth derivative of f(x)= e^x^2. I got f''(x)=2e^x^2 + 4x^2e^x^2 i need some help on find f''''(x) You have f(x) = ex2 then f'(x) = 2x*ex2 = 2x*f(x) f"(x) = (4x2  2))ex2 = f(x)*(4x2  2)) f"'(x)= f'(x)*(4x2

5x 3 = 11 + 12x combine like figures add 3 to both sides to remove the 3 5x= 14+ 12x Now I get confused. If I remove the 12x I have to subtract 12x from 5x which gives me an answer of 7x=14 would the correct answer thus be x=
