Answer:
-
Step-by-step explanation:
A root with square root or under root is only obtained when we take the square root of both sides. Remember that when we take a square root, there are two possible answers:
- One answer with positive square root
- One answer with negative square root
For example, for the equation:
If we take the square root of both sides, the answers will be:
Only getting one solution with square root is not possible. Solutions with square root always occur in pairs.
For given case, the roots are 6 and . Therefore, the 3rd root of the polynomial function f(x) had to be -
It seems you made error while writing option B, it should be - square root of 5.
Answer:
Step-by-step explanation:
we would like to figure out the differential coefficient of
remember that,
the differential coefficient of a function y is what is now called its derivative y', therefore let,
to do so distribute:
take derivative in both sides which yields:
by sum derivation rule we acquire:
Part-A: differentiating $e^{2x}$
the rule of composite function derivation is given by:
so let g(x) [2x] be u and transform it:
differentiate:
substitute back:
Part-B: differentiating ln(x)•e^2x
Product rule of differentiating is given by:
let
substitute
differentiate:
Final part:
substitute what we got:
and we're done!
