Evaluate. (-(5)/(2))^(2)=

Identify Base and Exponent: Identify the base and the exponent. In the expression (-(5)/(2))^(2), -(5)/(2) is the base raised to the exponent 2. Base: -(5)/(2) Exponent: 2Choose Expanded Form: Choose the expanded form of (-(5)/(2))^(2). The base is -(5)/(2) and the exponent is 2. So, (-(5)/(2))^(2) means -(5)/(2) is multiplied by itself once. Expanded Form of (-(5)/(2))^(2): (-(5)/(2)) × (-(5)/(2))Multiply to Simplify: (-(5)/(2))^(2) = (-(5)/(2)) × (-(5)/(2)) Multiply to write in simplest form. (-(5)/(2))^(2) = (-(5)/(2)) × (-(5)/(2)) = (25)/(4) The simplest form of (-(5)/(2))^(2) is (25)/(4).

\left(-\frac{5}{2}\right)^{2}=

Identify Base and Exponent: Identify the base and the exponent. $\newline$ In the expression $\left(-\frac{5}{2}\right)^{2}$ , $-\frac{5}{2}$ is the base raised to the exponent $2$ . $\newline$ Base: $-\frac{5}{2}$ $\newline$ Exponent: $2$
Choose Expanded Form: Choose the expanded form of $\left(-\frac{5}{2}\right)^{2}$ . The base is $-\frac{5}{2}$ and the exponent is $2$ . So, $\left(-\frac{5}{2}\right)^{2}$ means $-\frac{5}{2}$ is multiplied by itself once. Expanded Form of $\left(-\frac{5}{2}\right)^{2}$ : $\left(-\frac{5}{2}\right) \times \left(-\frac{5}{2}\right)$
Multiply to Simplify: $\left(-\frac{5}{2}\right)^{2} = \left(-\frac{5}{2}\right) \times \left(-\frac{5}{2}\right)$ $\newline$ Multiply to write in simplest form. $\newline$ $\left(-\frac{5}{2}\right)^{2}$ $\newline$ $= \left(-\frac{5}{2}\right) \times \left(-\frac{5}{2}\right)$ $\newline$ $= \frac{25}{4}$ $\newline$ The simplest form of $\left(-\frac{5}{2}\right)^{2}$ is $\frac{25}{4}$ .
