One ordered pair (a,b) satisfies the two equations ab^4 = 48 and ab^2 = 4. 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.)
ab4=48, ab2=4
ab4=(ab2)b2=4b2=48
b2=12, b=±2√3
If b has to be positive as specified possibly in your question, then type 2sqrt(3), if not, then type -2sqrt(3).
