help~ differentiation (1 Viewer)

[shkspeare]

hey how wud i differentiate x^4

=| i haven done my hw for about 2 months now lolz and test is up mon so im learning all my shit now haha

 

[Rahul]

answer would be 4x^3

follow the rule:
y=ax^n
y'=n.ax^(n-1)

 

[Viper]

If f(x) = x^n

f'(x) = nx^(n-1)


ie.. if f(x) = x^4,

f'(x) = 4x^3

This is basic year 11 2 unit mate... Im guessing you are having a mental blank or something??

Cheers
