Question

Help the character from Shoe find the square root of 225 .

Short answer

The square root of 225 is 15.

Step-by-step solution

Understand the Problem

The problem asks us to find the square root of 225. A square root of a number is a value that, when multiplied by itself, gives the original number.

Calculation of the Square Root

To find the square root of 225, we need to determine which number multiplied by itself equals 225. Since 15 multiplied by 15 equals 225, the square root of 225 is 15.

Verify the Solution

To ensure the solution is correct, we can check the multiplication: \(15 \times 15 = 225\). Since this statement is true, we have verified that the square root of 225 is indeed 15.

Key concepts

Mathematical Concepts

The concept of a square root is a fundamental one in mathematics. Whenever we talk about the square root of a number, we are discussing the value that multiplies by itself to give the original number. For instance, the square root of 225 is 15 because when you multiply 15 by itself, you get 225. This idea is tied to the broader mathematical concept of exponents, where finding a square root is essentially finding the exponent that equals 1/2, as in \(a^{1/2} = \sqrt{a}\).
Understanding square roots helps in other areas of math, such as solving quadratic equations or working with radical expressions. By knowing the square root, you're equipped to simplify complex equations and enhance your problem-solving skills.

Arithmetic

Arithmetic involves basic mathematical operations including addition, subtraction, multiplication, and division. Finding a square root is closely related to multiplication, as it involves identifying a number that, when multiplied by itself, leads to the given number. In the example of 225, discovering that 15 multiplied by 15 gives 225 illustrates a profound aspect of arithmetic. This process also showcases multiplication's inverse relationship with square roots.
With more complicated numbers, one might rely on estimation or employ algorithms, yet the principle remains consistent. Practicing arithmetic with square roots can enhance your numerical fluency and accuracy.

Problem Solving

Problem solving in mathematics often involves understanding the question, identifying the steps required, and verifying the result. Breaking down the task of finding the square root of 225, we first determine what is asked: calculating the square root. We then proceed by examining possible numbers whose product times themselves yields 225. This sequential approach aids in simplifying complex problems.
Verifying the answer is a crucial final step for problem solving. By checking, as we did with confirming \(15 \times 15 = 225\), we ensure the solution is correct. This builds confidence in your problem-solving abilities and ensures thorough understanding and accuracy in mathematics.
