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

 

b=[2/3]^(1/3)
