Question

which will have an output of 7.0?

>> from math import sqrt

>> sqrt(49)

>> from sqrt import math

>> sqrt(49)

>> from math import root

>> root(49)

>> from root import math

>> root(49)

Explanation:

In Python, to calculate the square - root, the correct way is to import the sqrt function from the math module. The square - root of 49 is 7.0. The correct import statement is from math import sqrt and then sqrt(49). The other import statements are incorrect as from sqrt import math and from root import math have wrong import directions, and there is no root function in the math module for simple square - root calculation like this.

Answer:

First option:

>> from math import sqrt

>> sqrt(49)
