J.G. has explained it for you. so let make it simple 2^1 = 2 2^2 = 2 x 2 = 4 2^3 = 2 x 2 x 2 = 8 2^4 = 2 x 2 x 2 x 2 = 16 2^5 = 2 x 2 x 2 x 2 x 2 = 32 so 2**5 is the same of 2^5.

3.0 is the result of square root of 9. python implicitly change int to float. you can also use math.sqrt(9) which give the same float result.

Some more explanations that hopefully help, if I'm not already repeating what was said xD. Math lesson 101. * is to multiply. ^ is exponent. x, y, n are letters that represent any number. 2^5 can be written as: 2*2*2*2*2 = 32. so x^n is defined as: x*x*x (n times). Though, it's a bit trickier with non-integer exponents. (An exponent is the number raised to x, in this case 'n') with x^(1/2). it's the same as the square root of x. Square root is some number y, that when squared will be equal to x. Squaring a number means to put it to the exponent 2. so if x = 9. some number squared that would equal 9 is 3. That is, 3^2 = 3*3 = 9.

Exponentation? Like exponents? Raising numbers to powers?

Hmm... This is something we learn in mathematics class. So, think of something easy. 2^2=4. Multiply 2 twice. 2*2=4. That's what exponents are, at least exponents greater than 1. take 5^3=5x5x5=125. Multiply the base (first number) n times, where n is the exponent. It gets way more complicated than that, but that is the basic idea. Does that help at all?

One note: '**' = '^' So 2^5. That is 2*2*2*2*2=32 And 9^.5=sqrt(9)=3. Have you learned exponents before?
