Hello

I am not able to use sqrt funtion & ^ power function. The runtime giving me error about this saying undefine symbol. which library to import to use this functions?

Try this:

```
import math
print math.sqrt(4) #square root
print math.pow(2,3) #power, or 2^3
print 2**3 #same thing
```

The carat (or ^) is a bitwise ‘or’ operator (I think)

EDIT: Oops! it’s an ‘xor’.
