Identify Expression: Identify the expression to be evaluated. We need to evaluate the expression (2r-5)^5, where (2r-5) is the base and 5 is the exponent.Expand Using Binomial Theorem: Expand the expression using the binomial theorem or by multiplying (2r-5) by itself five times. However, without a specific value for r, we cannot simplify the expression further. We can only expand it symbolically.Need Specific Value: Recognize that without a specific value for r, we cannot provide a numerical answer. The expression (2r-5)^5 is already in its simplest form without additional information. To proceed further, we would need a specific value for r.

(2r-5)^5

Identify Expression: Identify the expression to be evaluated. $\newline$ We need to evaluate the expression $(2r-5)^5$ , where $(2r-5)$ is the base and $5$ is the exponent.
Expand Using Binomial Theorem: Expand the expression using the binomial theorem or by multiplying $(2r-5)$ by itself $5$ times. $\newline$ However, without a specific value for $r$ , we cannot simplify the expression further. We can only expand it symbolically.
Need Specific Value: Recognize that without a specific value for $r$ , we cannot provide a numerical answer. The expression $(2r-5)^5$ is already in its simplest form without additional information. To proceed further, we would need a specific value for $r$ .
