Learn how to divide two exponents with fractional powers

The video tutorial covers exponent rules, focusing on multiplication and division of powers with the same base. It explains how to subtract exponents when bases differ, using the least common denominator (LCD) to handle fractions. The tutorial also demonstrates converting negative powers to positive and representing them as radicals.

What operation do you perform on the exponents when dividing powers with the same base?

• Add the exponents

• Multiply the exponents

• Subtract the exponents

• Divide the exponents

Why is it necessary to find a common denominator when adding or subtracting fractions?

• To make the fractions equal

• To convert fractions to decimals

• To ensure the fractions have the same base

• To simplify the fractions

What is the least common denominator (LCD) of the fractions 1/5 and 2/3?

• 10

• 15

• 3

• 5

How can a negative exponent be represented as a positive power?

• By subtracting 1 from the exponent

• By taking the reciprocal of the base

• By adding 1 to the exponent

• By multiplying the base by itself

How would you express 2 to the power of -7/15 as a radical?

• The 15th root of 2 to the 7th power

• The 7th root of 2 to the 15th power

• The 15th power of 2 to the 7th root

• The 7th power of 2 to the 15th root
