Use the power, product, and chain rules:
• product rule
• power rule for the first term, and power/chain rules for the second term:
• power rule
Now simplify.
You could also use logarithmic differentiation, which involves taking logarithms of both sides and differentiating with the chain rule.
On the right side, the logarithm of a product can be expanded as a sum of logarithms. Then use other properties of logarithms to simplify
Differentiate both sides and you end up with the same derivative:
Answer:
12 cm
Step-by-step explanation:
8 divided by 4 is 2
6 x 2 = 12
Answer:
- 2/9, 2/7, 1/10, 1/6, 1/4, 1/7, 1/16, 5/3
Step-by-step explanation:
A: 2/3 divided by 3
B: 6/7 divided by 3
C: 2/5 divided by 4
D: 5/6 divided by 5
E: 10/8 divided by 5
- 10/8 : 5 = 5/4 * 1/5 = 1/4
F: 4/7 divided by 4
G: 5/8 divided by 10
-
5/8 : 10 = 5/8*1/10 = 1/16
H: 20/6 divided by 2
- 20/6 : 2 = 10/3 * 1/2 = 5/3
<h2>
x = - 6 or, 1</h2>
Step-by-step explanation:
The given quadratic equation:
By factorisation mmethod,
⇒ x(x + 6) - 1(x + 6) = 0
⇒ (x + 6)(x - 1) = 0
⇒ x + 6 = 0 or, x - 1 = 0
⇒ x + 6 = 0 ⇒ x = - 6
⇒ x - 1 = 0 ⇒ x = 1
∴ x = - 6 or, 1
So... it has degree of 7, so based on the fundamental theorem of algebra....it can have at most 7 solutions
now.. you have <span>−4, −4i, 2i <--- there are two complex ones there
-4i or 0-4i and 2i or 0+2i
now.. bear in mind that, complex solutions never come all by their lonesome, they come with their sister, the conjugate
thus, that means 0-4i comes with 0+4i and 0+2i comes with 0-2i
that makes only 5 roots though
that simply means that, the -4 one, has a multiplicity of 3
as far as the B) and C) sections, check Descartes Rule of Signs
which surely you've covered already
