Simplifying Algebraic Fractions

The video tutorial covers simplifying expressions with negative exponents and subtracting fractions with different denominators. It begins with converting negative exponents to positive by flipping fractions, then breaks down expressions into simpler parts. The tutorial also explains factorizing denominators to find common terms and achieve a common denominator for fraction subtraction. Finally, it demonstrates how to subtract and simplify the resulting expression.

What is the first step in simplifying an expression with a negative exponent?

• Subtract the exponent from the base

• Add the exponent to the base

• Flip the fraction and change the exponent to positive

• Multiply the base by the exponent
