Answer:
The given expression is divisible by 3 for all natural values of x.
Step-by-step explanation:
The given expression is

For x=1,

9 is divisible by 3. So, the given statement is true for x=1.
Assumed that the given statement is true for n=k.

This expression is divisible by 3. So,
.... (1)
For x=k+1




Using equation (1), we get





This expression is also divisible by 3.
Therefore the given expression is divisible by 3 for all natural values of x.

3x²-y³ - y³ - z if x = 3, y = -2, z = -5
Simply plug in all the values :)
3(3²) - (-2³) - (-2³) - (-5)
Simplify.
3(9) + 2³ + 2³ + 5
Simplify.
27 + 8 + 8 + 5
Simplify.
35 + 13
Simplify.
