Is the Derivative Calculation Correct Despite the Notation Error?

In summary, the Power Rules in mathematics are a set of rules for simplifying expressions with exponents. These rules include the Product Rule, Quotient Rule, Power Rule, and Negative Exponent Rule. To apply the Power Rules, you must identify the base and exponent and apply the appropriate rule based on the operation. The Summation Rule, also known as the Sum Rule, governs the simplification of expressions with multiple terms being added or subtracted. It states that like terms can be combined by adding or subtracting their coefficients and keeping the base the same. The Power and Summation Rules can be used together to simplify more complex expressions. However, there are exceptions to these rules, such as when dealing with negative ex

Is this simplified?

Use the power rule and the summation rule to find f ' (x) and simplify where possible

f(x) = ((2x^3)/5) - x^2 +3/8

f ' (x) = d/dt(((2x^3)/5) - x^2 +3/8) = ((6x^2)/5) - 2x

Is this the right answer?

Looks fine from here.

Except, it should be d/dx...not d/dt !
 

1. What are the Power Rules in mathematics?

The Power Rules in mathematics are a set of rules that govern how to simplify and manipulate expressions with exponents. They include the Product Rule, Quotient Rule, Power Rule, and Negative Exponent Rule.

2. How do you apply the Power Rules to simplify expressions?

To apply the Power Rules, you must first identify the base and exponent in the expression. Then, apply the appropriate rule depending on the operation between the terms. For example, for the Product Rule, you would multiply the exponents when multiplying two terms with the same base.

3. What is the Summation Rule in mathematics?

The Summation Rule, also known as the Sum Rule, is a rule that governs the simplification of expressions with multiple terms being added or subtracted. It states that when adding or subtracting terms with the same base, you can combine the coefficients and keep the base the same.

4. Can the Power and Summation Rules be used together?

Yes, the Power and Summation Rules can be used together to simplify more complex expressions. First, you would apply the Power Rules to simplify the individual terms, and then use the Summation Rule to combine them.

5. Are there any exceptions to the Power and Summation Rules?

Yes, there are some exceptions to these rules, such as when dealing with negative exponents or fractions with exponents. It is important to carefully apply the rules and make note of any exceptions to ensure accurate simplification.
