Accepted Answer
The value a = 2 and b = 5 is makes the expression (5x²y²){-4xªy³) =−20xªyᵇ as true.Expression:An expression is set of numbers or variables combined using the operations +, -, * and /.Given,Here we have the expression (5x²y²){-4xªy³) =−20xªy°.Now, we have to the value of a and b which make both equation as equal.In order to get the value a and b, first, we have to solve the expression in the left hand side,To solve this type of equation, the first step is to combine the like terms, then we get,=> (5x²y²){-4xªy³) => (5 x -4) (x² xᵃ) (y² y³)Now, we have to do the multiplication on it, then we get,=> -20 xᵃ⁺² y²⁺³=> -20xᵃ⁺²y⁵Now, we have to equate both LHS and RHS, then we get,=> -20xᵃ⁺²y⁵ = -20xᵃyᵇWhile we looking into the equation, we have identified that the value of a is 2 and the value of b is 5.To know more about Expressions here.https://brainly.com/question/14083225#SPJ1
