Answer:
nx^(n-1).
Step-by-step explanation:
d/dx (x^n)
We multiply by n than subtract 1 from the exponent (n):
= n x^(n-1)
Numerical examples:
d(x^3) dx = 3 * x^(3-1)
= 3x^2.
d(2x^5)/dx = 5*2 x^(5-1)
= 10x^4.
 
        
             
        
        
        
(18 - x)^2
If (a - b)^2 then the answer is a^2 - 2ab + b^2
18^2 - 36x + x^2
The answer is x^2 - 36x + 324

-10 is equal to 5 subtracted from a number
Assume that the number is x
So the equation will be

we put x at first because in subtraction the number after the word "from" comes first
Now let us find x
We need to move 5 to the left side to find x, so add 5 to both sides

The number is
