Problem

Simplify 26÷negitive*13

The question asks for the simplification of the division of two numbers: 26 (the dividend) and -13 (the divisor). The operation involved here is division, and it appears that there's a typographical error with the word "negative," which should be "negative". The question is essentially requesting the result of dividing 26 by negative 13.

Solution:

Step 1: Simplify the expression by addressing the denominator.

  • Step 1.1: Apply the exponential function to the denominator. 26÷negative(e1)×13

  • Step 1.2: Repeat the application of the exponential function. 26÷negative(e1×e1)×13

  • Step 1.3: Utilize the exponentiation rule am×an=am+n. 26÷negativee1+1×13

  • Step 1.4: Perform the addition of the exponents. 26÷negativee2×13

  • Step 1.5: Combine the imaginary units by adding their exponents.

    • Step 1.5.1: Rearrange the imaginary units. 26÷neg(i×i)ativee2×13
    • Step 1.5.2: Multiply the imaginary units. 26÷negi2ativee2×13

Step 2: Replace i2 with 1. 26÷neg×1ativee2×13

Step 3: Express the division as a fraction. 26neg×1ativee2×13

Step 4: Position 1 before the 'neg' term. 261×(neg)ativee2×13

Step 5: Place the negative sign in front of the fraction. 26negativee2×13

Step 6: Execute the multiplication of 26negativee2 and 13.

  • Step 6.1: Multiply 13 by 1. 13×26negativee2
  • Step 6.2: Combine 13 with the fraction. 13×26negativee2
  • Step 6.3: Multiply 13 and 26. 338negativee2

Step 7: Bring the negative sign out in front of the fraction. 338negativee2

Knowledge Notes:

The problem-solving process involves simplifying an expression that contains a division by a negative exponentiated value. The steps include manipulating the expression using properties of exponents and imaginary numbers. Here are the relevant knowledge points:

  1. Exponentiation: Raising a number to a power, such as e1, where e is the base of the natural logarithm.

  2. Power Rule: A rule for simplifying expressions with exponents, stating that am×an=am+n.

  3. Imaginary Unit: The imaginary unit i is defined as 1, and i2=1.

  4. Negative Numbers: A negative number times another negative number results in a positive number.

  5. Fraction Representation: Division can be represented as a fraction, where the numerator is the dividend and the denominator is the divisor.

  6. Combining Terms: Multiplication and division operations are performed to combine terms into a simpler form.

  7. Negative Sign Placement: A negative sign can be moved in front of a fraction to indicate that the entire fraction is negative.

The solution involves using these principles to simplify the given expression step by step, ensuring that the negative signs and imaginary units are handled correctly to arrive at the final simplified result.
