Problem 33 - Algebra 1

Question

Write the expression in exponential form. five squared

Step-by-Step Solution

Answer

The exponential form of 'five squared' is \(5^2\).

Step 1: Recognize the Base

The word 'five' is recognized as the base number, which is 5 in numerical form.

Step 2: Recognize the Exponent

The term 'squared' is recognized as referring to the power of 2, which is our exponent.

Step 3: Write in Exponential Form

Combine the recognized base and exponent to write the expression in exponential form. Five squared becomes \(5^2\).

Key Concepts

Understanding Base and Exponent

In mathematics, understanding the concept of base and exponent is fundamental when dealing with exponents. The **base** is the number that is multiplied by itself, while the **exponent** indicates how many times the base is used in the multiplication. To interpret any exponential expression, it's essential to identify these two components. For example, in the expression \(5^2\), the number 5 is the base.

• The base tells us what number is being repeatedly multiplied.
• The exponent tells us how many times we multiply that base by itself.

Together, base and exponent succinctly convey mathematical operations that would otherwise require long multiplication to express.

Writing in Exponential Form

When we talk about writing in exponential form, we are referring to using a mathematical shorthand for repeated multiplication of the same number. This form comprises a base and an exponent written as \(b^n\), where \(b\) is the base and \(n\) is the exponent. Exponential form is handy because it simplifies calculations and allows us to easily communicate large operations. For example, instead of writing 5 multiplied by itself, which appears as \(5 \times 5\), we simply write it as \(5^2\). Here:

• 5 is the base, representing the number being multiplied.
• 2 is the exponent, showing that the base is used as a factor twice.

This simplicity is why exponential notation is widespread in mathematics, simplifying everything from simple multiplication to advanced calculations in fields like physics and engineering.

Exploring Squared in Math

In math, when we say a number is "squared," we mean the number is raised to the power of 2. Squaring is one of the most common examples of using exponents. It is just another way of saying that you multiply a number by itself.So, when you see the expression \(5^2\), you are seeing 5 squared. It means:

• 5 is multiplied by itself once, which is \(5 \times 5\).
• The result is 25.

Squaring doesn't just stay within arithmetic. It's also a fundamental operation in algebra, geometry, and calculus, often appearing in formulas concerning areas and sequences. Remember, every squared number is the result of its base number used twice as a factor.
