Best ResponseYou've already chosen the best response.0\(\Large \dfrac{a^m}{a^n} = a^{m  n} \) \(\Large \dfrac{f^9h^{23}}{f^3h^{17}} = f^{9  3}h^{23  17} = f^6 h^6 \)

Best ResponseYou've already chosen the best response.0Nope just like this: \[(9x − 4)(9x + 4) = ax^2 − b\]

Best ResponseYou've already chosen the best response.1when I square the b it is just part of the formula of difference of squares

Best ResponseYou've already chosen the best response.1i can use any variable for this formula: When I said (ab)•(a+b)=a²b² i could have said also (xy)•(x+y)=x²y² where x and y are just any thing in general (and so was "b" when i posted it, any thing in general, and not that particular b that you had in "ax²b"

Best ResponseYou've already chosen the best response.1in any case, you know that (9x+4)(9x4) is the product that gievs you the area of the region. Right?

Best ResponseYou've already chosen the best response.1and you are given that the area of the region is ax²b

Best ResponseYou've already chosen the best response.1therefore (9x+4)(9x4)=ax²b

Best ResponseYou've already chosen the best response.1by the rule of the "difference of square" it follws that: (9x)²  (4)² =ax²b

Best ResponseYou've already chosen the best response.1simplify the left side, and then the value of a should be easy.

Best ResponseYou've already chosen the best response.1(9x)²=9²•x²=81x² right?

Best ResponseYou've already chosen the best response.1(9x+4)(9x4)=ax²b (9x)²  (4)² =ax²b 81x²  16 =ax²b
