Plz I cant get this
One ordered pair (a,b) satisfies the two equations ab^4 = 48 and ab = 72. What is the value of b in this ordered pair? (Note: you may have to use the Tab key to get your cursor into the middle answer box.)
What do you mean "I can't get this" ? Did you try?
What happens if you divide one by the other like this:
[ab^4] / [ab] = 48 / 72
b^3 = 2 / 3
