Question

what is the derivative of 3, x^2,X^3,X^5,X, 7x?

Answer 1

find the derivative by using the formual \[nx ^{n-1}\]

Answer 2

n is the exponent

Answer 3

okay, let me find out and i will ask you if its correct or not.

Answer 4

X^2+= 2x
X^3= 3x square
X^5= 5x^4
x= 1/x
7x= 7
??

Answer 5

The derivative of x is 1

Answer 6

yes thats right, except for x, it doesnt equal 1/x, it equals 1

Answer 7

derivative of x is 1, other answers look good

Answer 8

How do you get that 1?

Answer 9

because x is actually the same as x^1 and x^(1 - 1) = x^0 and anything raised to the power of 0 is 1

Answer 10

thats why 7x becomes just 7 because it turns int 7* x^0 which is just 7*1 = 7

Answer 11

yeah, i got it now.

Answer 12

Thank you so much.
