How do you create a restriction for √z + 8=13 ?
√z = 13 - 8√z = 5z = 5²z = 25In this case the z can be any number, however z cannot be less than 0 and that is the restriction. (for example; √-1 = irrational number, cannot be solved.)
I found this on the internet I hope it helps
√z = 13 - 8√z = 5z = 5²z = 25
its on the answer key xD
