- Actual question is :
(yz is not in power of x)
What is the maximum value of (v^x) - yz. If the value of v,x,y,z have to be chosen from the set A where A(-3,-2,-1,0,1,2,3)
a) 9
b) 12
c) 15
d) none of these
Explanation is
To maximize the value of (v^x) - yz, we make yz negative and v^x as maximum as possible using given value.
(v^x)−yz=(−3)2−(−3×2) = 15

- if we take v=3,x=2,y=-3,z=1
then we get 3^5=243 (MAX)

- for question v^(x-yz)
-3^( 2 - 3 * -2 )
=> -3^8
=> 6561 - 9 years agoHelpfull: Yes(2) No(3)
- let take v=3...x=1,y=-3,z=2...now solving the above equatn result is 2187 which is max. den any value taken in otherway

- are is the right answer

- v^x-yz
for max x-yz>0
x>yz
max(x)=6,min(y)=0
max(x-yz)=6
v^6=?
if max(v)=3
then max(3^6)=729 - 9 years agoHelpfull: Yes(0) No(2)
- v=3, x=2, y=-3,z=-1

- (-3)^3-2(-2)=27+4=31
- 9 years agoHelpfull: Yes(0) No(7)
- Put x = 2,v = 3 then
v^x = 9
Now put y = -3 , z = 3
then yz= -9
thus,we have
v^x - yz = 9 - (-9) = 18.
