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.)

solve each equation for a, then set them = to each other and solve for B

 

a= 48/b^4

a=72/b

 

48/b^4 = 72/b

48/b^3=72

1/b^3=3/2

b^3=2/3

cuberoot b^3 = Cuberoot (2/3)

b= (2/3)^1/3

b= .87
