Answer: m=4

Step-by-step explanation: (9)^2m÷9^-5=9^13

                                         ⇒ (9)^(2m-(-5))=9^13

                                         ⇒ (9)^2m+5=9^13

                                On Comprising their powers,

                                         ⇒2m+5=13

                                         ⇒2m=13-5

                                         ⇒2m=8

                                         ⇒m=8÷2

                                         ∴m=4

Mark me as the brainliest
