<p>The<a>square</a><a>of</a>a<a>number</a>is the<a>product</a>of the number itself. The square of 3 is 3 × 3. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in<a>math</a>as 3², where 3 is the<a>base</a>and 2 is the<a>exponent</a>. The square of a positive and a negative number is always positive. For example, 5² = 25; -5² = 25. The square of 3 is 3 × 3 = 9. Square of 3 in exponential form: 3² Square of 3 in arithmetic form: 3 × 3</p>

<p>Using a<a>calculator</a>to find the square of a number is the easiest method. Let’s learn how to use a calculator to find the square of 3. Step 1: Enter the number in the calculator. Enter 3 in the calculator. Step 2: Multiply the number by itself using the<a>multiplication</a>button (×). That is 3 × 3. Step 3: Press the equal button to find the answer. Here, the square of 3 is 9. Tips and Tricks for the Square of 3 Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students. The square of an<a>even number</a>is always an even number. For example, 6² = 36 The square of an<a>odd number</a>is always an odd number. For example, 5² = 25 The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9. If the<a>square root</a>of a number is a<a>fraction</a>or a<a>decimal</a>, then the number is not a perfect square. For example, √1.44 = 1.2 The square root of a perfect square is always a whole number. For example, √144 = 12.</p>

<p>Okay, lets begin</p>
28
<p>The length of the garden = 3 meters The cost to tile 1 square meter of garden = 5 dollars. To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a² Here a = 3 Therefore, the area of the garden = 3² = 3 × 3 = 9. The cost to tile the garden = 9 × 5 = 45. The total cost = 45 dollars</p>
