Just plug in the value of x, y and z in the expression...

anonymous · Answer

3^3-2(5)^2-3(3)^3+(-3)^4= 
But how do i do all of this to get to the end result

phi · Answer

one term at a time  (and be careful)

what is 3^3 ?  i.e. what is 3*3*3?   write down the result
then move on to the next term
-2 * 5*5 = ?
write it down

can you do that ?

anonymous · Answer

3^3=9? 
-2 *5=10*5=50?
Am i right or no?

phi · Answer

3^3 means 3*3*3

that is not 9
