Question

x - x power 2 = ?

please help me​

Answer 1

Answer:

x-x^2=0

x(1-x)=0

So

either x=0 or x= 1

Answer 2

Answer:

How do you differentiate 2 to the power x?

let y=2x {take natural logs of both sides}

ln y = ln(2x) {use rules of logs to change right hand side}

lny = xln2 {differentiate implicitly}

1/y . dy/dx = ln2 {make dy/dx the subject}

dy/ dx = y ln2 {write y in terms of x)
