## anonymous 3 years ago I'm stuck into the 1.4 exercise when it asks me to print some equation. How can I do the square root operation correctly in python?

First you have to "import math" in order that you can call the square root function "math.sqrt(number)". Or you can try to squaring to the broken-number 1/2. "number ** (0.5)"

or you can also do with negative number "number**(-2)"

@zlatandebian number**(-2) is equivalent to : $\frac{ 1 }{ number ^{2} }$ Not the square root.
