Explanation:
#"the initial statement is "Rprop1/I^2#
#"to convert to an equation multiply by k the constant"#
#"of variation"#
#rArrR=kxx1/I^2=k/I^2#
#"to find k use the given condition"#
#I=25" when "R=100#
#R=k/I^2rArrk=RI^2=100xx25^2=62500#
#"the equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(R=62500/I^2)color(white)(2/2)|)))#
