Question

Q.8. What are the values of the following Python expressions?

2** (3**2)
(2**3)**2
2**3**2

a) 64,512, 64
b) 64, 64, 64
c) 512, 512, 512
d) 512, 64, 512​

Answer 1

d) 512,64,512

Explanation

2** (3**2)

First bracket which is

${2}^{( {3}^{2}) } = {2}^{9} = 512$

(2**3)**2

First bracket

$({ {2}^{3}) }^{2} = {8}^{2} = 64$

2**3**2

It will be

${2}^{ {3}^{2} } = {2}^{9} = 512$

Answer 2

The values of the following Python expressions is 512, 64, 512​

d) 512, 64, 512​

Extra Information

*‎* is power operator. Expressions in question will look like this in mathematical terms.

2*‎* (3*‎*2) = $2^{(3^{2})}$ = $2^{9}$ = 512

(2*‎*3)*‎*2 = $(2^{3})^{2}$ = $8^{2}$ = 64

2*‎*3*‎*2 = $2^{3^{2} }$ = $2^{9}$ = 512

There are various types of Arithmetic Operators in Python such as

(A) + operator

It is used to add two operands

Example

print(5+3)

The output will be 8

(B) - operator

It is used to subtract two operands

Example

print(5-3)

The output will be 2

(C) * operator

It is used to multiply two operands

Example

print(5*3)

The output will be 15

(D) / operator

It is used to divide the operands

Example

print(5/3)

The output will be 1.6666666666666667

(E) // operator

It is used to divide the operands

Example

print(5//3)

The output will be 1

(F) % operator

It is used to divide the operands and return the remainder

Example

print(5%3)

The output will be 2

(G) *‏‏‎‎‎‎* operator

It is used to raise one operand to the power of another.

Example

print(5*‎*3)

The output will be 125

In mathematical terms, it will be like 5³ which is 125

Python is created by Guido van Rossum and came into existence in 1991. It is a high-level and general programming language. It is a very lucid programming language as it has a good language construct and object-oriented approach. It is dynamically typed and garbage-collected.
