We use the product rule with u=x and v=ln(x) (so u'=1 andv'=1/x) to differentiate xln(x) to ln(x)+1, and -x just differentiates to -1, hence we have. f'(x)=ln(x).
Now note that ln(x^3)=3ln(x) using p...

x=1, y=2
x=-2/5, y=-11/5

1. 36^1/2
   = 6(The square root of 36 is 6)
   2) 23⁰
   = 1(Anything to the power of 0 is 1)
   3) 27^-2/3
   = 3^-2 = 1/3²= 1/9

Use Pythagoras' theorem. a² + b² = c². The longest side of the triangle is the hypotenuse, and it is the side opposite the right angle. We use the length of this side as '...

The easiest way is probably to write a table with all of the X and Y values. Write out all of the x values and substitute them into the formula to see what value of Y you need to get the value of 3.X Y-3 ...
