Introduction

In mathematics, we often come across numbers in different bases and exponents. In this article, we will focus on simplifying the expression 11 base 2 to the power 2. This involves understanding the concept of base and exponent, and then applying the rules of arithmetic operations to simplify the expression.

Understanding Base and Exponent

Before we dive into simplifying the expression, let's understand the concept of base and exponent. A base is the number that is being raised to a power, and an exponent is the number that is being multiplied by the base. In the expression 11 base 2 to the power 2, 2 is the base and 2 is the exponent.

What is Base 2?

Base 2, also known as binary, is a number system that uses only two digits: 0 and 1. It is the most basic number system and is used in computer programming and electronics. In base 2, the place values are powers of 2, starting from 2^0.

What is Exponent 2?

Exponent 2 means that the base 2 is being multiplied by itself 2 times. In other words, 2^2 = 2 × 2 = 4.

Simplifying 11 Base 2 to the Power 2

Now that we understand the concept of base and exponent, let's simplify the expression 11 base 2 to the power 2. To do this, we need to convert the base 2 to decimal (base 10) and then raise it to the power 2.

Converting Base 2 to Decimal

To convert base 2 to decimal, we need to multiply each digit of the base 2 number by its corresponding place value and then add them up. In this case, the base 2 number is 11, which is equal to 1 × 2^1 + 1 × 2^0 = 2 + 1 = 3 in decimal.

Raising the Decimal Number to the Power 2

Now that we have the decimal equivalent of the base 2 number, we can raise it to the power 2. In this case, 3^2 = 3 × 3 = 9.

Conclusion

In conclusion, simplifying the expression 11 base 2 to the power 2 involves understanding the concept of base and exponent, converting the base 2 number to decimal, and then raising the decimal number to the power 2. By following these steps, we can simplify the expression and arrive at the final answer.
