This code will generally not run, as there is nothing inside of the ( and ) of the print statement. Try displaying the result of the following comparisons (using the variables a,b,c,d and x) using the print statement:

• Is $\pi^2$ < 10?$ (hint: print(math.pi^2 < 10))
• Is $b^2>b$?
• Is $\pi^2 > a$?
• Is $a+b == b+a$?
• Is $b-a > 0$?
• Is $a-a=0$?
• Is $ab+0 == ab$?
• Is $1*a == a$?
• Is $0+a==a$?
• Is $(a+b)(a-b)==a^2-b^2$?
• Is $(a+b)(a+b)==a^2+2ab+b^2$?
• If $a>c$ and $c>d$ then is $a>d$ (use 3 print statements for this one)?
• If $a>b$ then is $1/a>1/b$?
• Is $e^x>1+x$ for any value of $x$? (Hint: $e^x$ is math.exp(x) in computer programming).
• Is $x^x\ge\left(\frac{1}{e}\right)^\frac{1}{e}$ for any value of $x$?
• Is $a^a+b^a\ge a^b+b^a$?
• Is $(1+x)^r\ge 1+rx$ (for any number $r$)?

Hint: Don't forget that computers don't know how to multiple automatically. So, something like $2ab$ has to be programmed in as 2*a*b. ×
