Answer:
Some of the Exponents = -2 that is true, not 2.
Step-by-step explanation:
Let's check one at a time.
(a)The 6 without an exponent is equivalent to the 6 having a 0 exponent.
and
= 6 (no exponent. 6
1 therefore this statement is False.
(b)The sum of the exponents is -2.
let's check , if the base is same we can add the exponents that is the exponent rule.(well established).
if we add exponents in the given expression we get.
, therefore we can see that the sum of the exponents = -2 this is true.
(c) An equivalent expression is 65.6-7, lets evaluate our above expression, it is equal to
which we can see that
,therefore this statement is false as well.
Answer:
(a) 
(b) 
Step-by-step explanation:
The given function is
.... (1)
According to the first principle of the derivative,






Cancel out common factors.

By applying limit, we get


.... (2)
Therefore
.
(b)
Put x=2, to find the y-coordinate of point of tangency.

The coordinates of point of tangency are (2,0.25).
The slope of tangent at x=2 is

Substitute x=2 in equation 2.

The slope of the tangent line at x=2 is -0.25.
The slope of tangent is -0.25 and the tangent passes through the point (2,0.25).
Using point slope form the equation of tangent is





Therefore the equation of the tangent line at x=2 is y=-0.25x+0.75.
