Identify base and exponent: Identify the base and the exponent. In the expression 7^2, 7 is the base raised to the exponent 2. Base: 7 Exponent: 2Choose expanded form: Choose the expanded form of 7^2. The base is 7 and the exponent is 2. So, 7^2 means 7 is multiplied by itself 2 times. Expanded Form of 7^2: 7 × 7Multiply to simplest form: 7^2 = 7 × 7 Multiply to write in simplest form. 7^2 = 7 × 7 = 49 The simplest form of 7^2 is 49.

Identify base and exponent: Identify the base and the exponent. $\newline$ In the expression $7^2$ , $7$ is the base raised to the exponent $2$ . $\newline$ Base: $7$ $\newline$ Exponent: $2$
Choose expanded form: Choose the expanded form of $7^2$ . $\newline$ The base is $7$ and the exponent is $2$ . $\newline$ So, $7^2$ means $7$ is multiplied by itself $2$ times. $\newline$ Expanded Form of $7^2$ : $\newline$ $7 \times 7$
Multiply to simplest form: $7^2 = 7 \times 7$ $\newline$ Multiply to write in simplest form. $\newline$ $7^2$ $\newline$ $= 7 \times 7$ $\newline$ $= 49$ $\newline$ The simplest form of $7^2$ is $49$ .
