Identify and apply quotient rule: Identify the expression and apply the quotient rule for exponents. The expression is u23/(u23⋅u21). According to the quotient rule, when we divide like bases, we subtract the exponents: am/an=am−n.
Apply product rule to denominator: Apply the product rule for exponents to the denominator.The product rule states that when we multiply like bases, we add the exponents: am×an=a(m+n). So, u23×u21=u(23+21).
Perform exponent addition: Perform the addition in the exponent.Add the exponents in the denominator: 23+21=24=2. So, u23×u21=u2.
Apply quotient rule to original expression: Apply the quotient rule to the original expression.Now we have u23/u2. Using the quotient rule: u23−2=u23−24.
Perform exponent subtraction: Perform the subtraction in the exponent.Subtract the exponents: 23−24=−21. So, u23/u2=u−21.
Write final answer: Write the final answer with a positive exponent.Since we want the exponent to be positive, we can write u−1/2 as 1/u1/2.
