Calculate 7² as an Integer: Converting Power to Standard Form

Question

Write the following as an integer:

$7^2=$

00:00 Solve

00:03 Let's use the power formula

00:06 Any number (X) to the power of (N)

00:09 equals X multiplied by itself N times

00:17 Let's use this formula in our exercise

00:22 Let's break down the power into multiplications

00:29 Let's calculate the multiplications

00:32 And this is the solution to the question

To solve this problem, we need to evaluate the expression $7^2$ . This expression means $7$ multiplied by itself, due to the exponent $2$ .

Step 1: Identify the base and exponent — here the base is $7$ and the exponent is $2$ .
Step 2: Apply the definition of exponents: calculate $7 \times 7$ .

Now, let's perform the calculation:

$7 \times 7 = 49$ .

Therefore, the integer value of $7^2$ is $\textbf{49}$ .
