2**3**2= 512. Why?

Question

So I was doing one of the Python 3 lessons (Basic Concepts, Other Numerical Operations) and I reached the Exponentation point. I understand how you raise one number to the power of another, but how do chained exponentations work?

Answer 1

Right to left

2**3**2 == 2^(3^2)

first 3**2 == 9
then 2**9 == 512

Answer 2

** means raised to power so first we take 3**2 which is 3 square = 9 .
Then we take 2**9 which is 2 power 9 which is 512 .Hope it helps 🙇🏻‍♂️

Answer 3

Cause python treat 2**3**2 as 2**3**2=2**9=512

Answer 4

*=multiplication
**=power

Answer 5

Himanshu Shah Whatever 🤦 Comparing Python to HTML is pointless and saying something wrong about HTML is misinformation. The time you are wasting arguing with me can be used to remove that misinformation from your answer. Good luck.

Answer 6

You can override the default order R-->L by using parentheses.... for exponentiation 🤔

Answer 7

x**y means x^y
in cases like this x**y**z, you have to calculate from rigth to left, i mean x^(y^z)
in your code 2^(3^2) = 2^9 = 512
is it clear?

Answer 8

In python power operator is ** . So in order to simplify expression we need to divide it into parts. 2**3=2^3, 3**2=3^2=9 => 2**3**2=2^(3^2)=2^9=512

Answer 9

Himanshu Shah 4² is not 16. It is 4².

Answer 10

Himanshu Shah Well, here is what I can see in your answer.
<<<
Eg. 4 ² answer is 16.
<<<

That is not true. At least, for the majority of browsers it renders 4² not 16.

Answer 11

Don't forget computer reads code from up to down and from right to left

Answer 12

you can also do this using the pow() function

Answer 13

2**3**2=512
2 to the power 3 =2^3=8
Similarly 8 to the power 3
8^3=512

2^3=8
8^3=512

Answer 14

2**3**2 is calculated as :
** Is an exponential operator
So, first 3**2 is calculated which is 9
= 2**9
=512

Answer 15

Because 2**3**2 = 2^(3^2) = 2^9 = 512
This is different from (2**3)**2 , which is (2^3)^2 = 8^2 = 64

Answer 16

Well I am at the Lambdas point and looking at this question, you use associativity property of operations. So:2**3**2=2**(3**2). "**" means exponent where the first number is the base and the other is exponent.So we get 2**9=512 In python the first number is the variable so other nunbers are placed in the brackets to be worked with, before the first number in the expression is used as the base.
In short, (2**3)*2=64 which is wrong.

Answer 17

2**3**2
Square of 3 is 9 2**9
2⁹=512

Answer 18

That's equal to 2**9 which is equal to 512

Answer 19

2**3**2
3^2=9
2**9 (2^9)
=512

Answer 20

In python, ** means 'to the power of'. So 2**3**2 = 2**9 (because 3^2 = 3x3 = 9). Then, 2**9 = 512 (because 2^9 = 2x2x2x2x2x2x2x2x2 = 512)
