Derivative Notation

Basic Power Rule

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

y = ∛x

x = 27

Step 2: Differentiate

[Function] Rewrite [Exponential Rule - Root Rewrite]: $\displaystyle y = x^{\frac{1}{3}}$
Basic Power Rule: $\displaystyle y' = \frac{1}{3}x^{\frac{1}{3} - 1}$
Simplify: $\displaystyle y' = \frac{1}{3}x^{-\frac{2}{3}}$
Rewrite [Exponential Rule - Rewrite]: $\displaystyle y' = \frac{1}{3x^{\frac{2}{3}}}$

Step 3: Solve

Substitute in x [Derivative]: $\displaystyle y'(27) = \frac{1}{3(27)^{\frac{2}{3}}}$
Evaluate exponents: $\displaystyle y'(27) = \frac{1}{3(9)}$
Multiply: $\displaystyle y'(27) = \frac{1}{27}$

A 3 pound pork loin can be cut into 10 pork chops with equal weight. How many ounces is each pork chop?

Misha Larkins [42]

Answer

Find out the how many ounces is each pork chop .

To prove

Relationship between pound and ounce .

1 pound = 16 ounce

As given

A 3 pound pork loin can be cut into 10 pork chops with equal weight.

Now for 3 pound pork loin = 3 × 16

= 48 ounces

now 48 ounces of pork loin can be cut into 10 pork chops with equal weight.

Than

$weight\ of\ each\ pork\ chops = \frac{48}{10}$

= 4.8 ounces

Therefore the weight of each ounce be 4.8 ounces .
