There are 2 ways. One is to use the Power Function. So to get 10² and get the value 100, you would type:
=Power(10,2)
You can also use the ^ symbol like this:
=10^2
y=(1/(sqrt(2*22/7)))*((e)power-((X squred)/2))
integral of e to the power -x is -e to the power -x
The first derivative of e to the x power is e to the power of x.
The power law of indices says: (x^a)^b = x^(ab) = x^(ba) = (x^b)^a → e^(2x) = (e^x)² but e^x = 2 → e^(2x) = (e^x)² = 2² = 4
The normal way to write this is: x3 (meaning x cubed / x to the third power).
e^x/1-e^x
d/dx (e-x) = -e-x
f(x) = (x^2)(e^x)f'(x) = e^x((x^2)+2x) - i thinkf"(x) = ?--------f(x) = (x^2)(e^x)apply the power rulef'(x) = (x^2)(e^x) + (2x)(e^x)apply the power rule to the first part and apply the power rule to the second part, then add those togetherf''(x) = [(x^2)(e^x) + (2x)(e^x)] + [(2x)(e^x) + (2)(e^x)]simplifyf''(x) = (e^x)(x^2 + 4x +2)I got it right. It checked out on my calculator.
2 squared, 22 or 2^2. In some old programming languages 2**2, but this should be avoided since it is no longer standard. Excel, for example interprets "x**y" as "x times 10 to the power y"
e^(3lnx)=e^[ln(x^3)]=x^3
x5 can be read as x to the power of 5 or more commonly as x to the fifth power.
