Im having trouble with 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.)

ab^4 = 48     then a = 48/b^4

 

sub into the second equation

48/b^4  * b = 72

48/72 = b^3 

b = .87358      then    a = 82.4194
