Identify base and exponent: Identify the base and the exponent. In the expression 9^2, 9 is the base raised to the exponent 2. Base: 9 Exponent: 2Choose expanded form: Choose the expanded form of 9^2. The base is 9 and the exponent is 2. So, 9^2 means 9 is multiplied by itself 2 times. Expanded Form of 9^2: 9 × 9Multiply to simplest form: 9^2 = 9 × 9 Multiply to write in simplest form. 9^2 = 9 × 9 = 81 The simplest form of 9^2 is 81.

Identify base and exponent: Identify the base and the exponent. $\newline$ In the expression $9^2$ , $9$ is the base raised to the exponent $2$ . $\newline$ Base: $9$ $\newline$ Exponent: $2$
Choose expanded form: Choose the expanded form of $9^2$ . $\newline$ The base is $9$ and the exponent is $2$ . $\newline$ So, $9^2$ means $9$ is multiplied by itself $2$ times. $\newline$ Expanded Form of $9^2$ : $\newline$ $9 \times 9$
Multiply to simplest form: $9^2 = 9 \times 9$ $\newline$ Multiply to write in simplest form. $\newline$ $9^2$ $\newline$ $= 9 \times 9$ $\newline$ $= 81$ $\newline$ The simplest form of $9^2$ is $81$ .
