What will be printed in the following code? import math num = math.pow(4, 3) print (num % 9) 1.0,3.0,2.0,4.0

Answer 1

Let's break down the provided code step by step:

1. The code imports the math module.
2. It then calculates num using math.pow(4, 3).
   • math.pow(4, 3) computes \( 4^3 \) which is \( 64.0 \) (as math.pow returns a float).
3. Next, the modulo operation num % 9 is performed.
   • Here, \( 64.0 \mod 9 \) is calculated. To do this, we find out how much 64 is greater than the nearest multiple of 9:
     • The multiples of 9 are \( 0, 9, 18, 27, 36, 45, 54, 63, 72, \ldots \)
     • The largest multiple of 9 that is less than 64 is 63.
     • Therefore, \( 64 - 63 = 1 \).
   • Thus, \( 64.0 \mod 9 = 1.0 \).
4. Finally, print(num % 9) is executed, which will print 1.0.

Hence, the output of the code will be:

1.0
