the ^-4 cancels out the ^-1, (two negatives equal a positive) so your left with (3mn/2)^4
3x3x3x3 =81
2x2x2x2 =16
m^4
n^4
it should look like
81m^4n^4
LINE
16

Its the building block for matrix calculus, and that can be a very useful tool for price prediction and other forcasting models. And its good brain exersise |

I hate brain exercises! I would rather exercise my dogs!
But thats what all my highschool teachers told me, when I told them I will never use this, they would say "its for problem solving skills". To this day it has yet to help me solve any problems haha

((3mn/2)exponent -1)exponent -4
[(3mn/2)^-1]^-4
simplifies to: 81 m^4 n^4 / 16

Man, I feel sorry for my kids. They are screwed unless thier momma remembers this stuff. If I dont need it to calculate drug dosages or drip rates for EMS or to figure pump pressures while pumping the engine, I dont remember any of it. Its kinda sad cause I was pretty good at it when I set my mind to it.
