[tex]3^2+3[2^3( \sqrt{49}-2^2)(3^2-2^3)-2^2] [/tex]
Right off the bat, this may look crazy, but if we take it step by step, it will be much easier. So, let's take it step by step. If any step doesn't make sense to you, you can always hmu.
[tex]9+3[8( 7-4)(9-8)-4][/tex]
[tex]9+3[8( 3)(1)-4] = 9+3[24-4] = 9+3[20][/tex]
[tex]9+60 = 69[/tex]
Your answer is 69.
