Exponents and Distribution Concepts

The video tutorial explains how to simplify the expression 3Z to the negative third power times the quantity of 5Z to the seventh plus 8Z to the sixth. The instructor demonstrates distributing the negative exponent term across the expression, multiplying terms, and adding exponents to eliminate the negative exponent. The final simplified expression is 15Z to the fourth plus 24Z to the third, with no negative exponents remaining.

What is the initial expression that needs to be simplified?

• 3z to the negative third power times 5z to the seventh

• 3z to the third power times (5z to the seventh plus 8z to the sixth)

• 5z to the seventh plus 8z to the sixth

• 3z to the negative third power times (5z to the seventh plus 8z to the sixth)

Why is it better to distribute the negative exponent rather than moving it to the denominator?

• It makes the expression more complex

• It is mathematically incorrect to move it

• It makes the expression longer

• It helps in eliminating the negative exponent

What is the first step in simplifying the given expression?

• Add all the exponents

• Multiply all the coefficients

• Distribute the negative exponent

• Move the negative exponent to the denominator

What is the purpose of distributing the negative exponent in this problem?

• To make the expression more complex

• To make the expression longer

• To change the base of the expression

• To eliminate the negative exponent

What happens when you multiply 3z to the negative third power with 5z to the seventh?

• You get 15z to the negative fourth

• You get 15z to the fourth

• You get 15z to the seventh

• You get 15z to the tenth
