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.)
+36916 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
