Identify base and exponent: Identify the base and the exponent. In the expression 0.7^2, 0.7 is the base raised to the exponent 2. Base: 0.7 Exponent: 2Choose expanded form: Choose the expanded form of 0.7^2. The base is 0.7 and the exponent is 2. So, 0.7^2 means 0.7 is multiplied by itself 2 times. Expanded Form of 0.7^2: 0.7 × 0.7Multiply to simplify: 0.7^2 = 0.7 × 0.7 Multiply to write in simplest form. 0.7^2 = 0.7 × 0.7 = 0.49 The simplest form of 0.7^2 is 0.49.

Identify base and exponent: Identify the base and the exponent. $\newline$ In the expression $0.7^2$ , $0.7$ is the base raised to the exponent $2$ . $\newline$ Base: $0.7$ $\newline$ Exponent: $2$
Choose expanded form: Choose the expanded form of $0.7^2$ . $\newline$ The base is $0.7$ and the exponent is $2$ . $\newline$ So, $0.7^2$ means $0.7$ is multiplied by itself $2$ times. $\newline$ Expanded Form of $0.7^2$ : $\newline$ $0.7 \times 0.7$
Multiply to simplify: $0.7^2 = 0.7 \times 0.7$ $\newline$ Multiply to write in simplest form. $\newline$ $0.7^2$ $\newline$ $= 0.7 \times 0.7$ $\newline$ $= 0.49$ $\newline$ The simplest form of $0.7^2$ is $0.49$ .
