Q. Rewrite the expression in the form yn.(y−21)4=□
Identify base and exponents: Identify the base and the exponents in the expression (y−(1)/(2))4. The base is y and the exponents are −21 and 4. We need to apply the power of a power rule, which states that (am)n=am∗n.
Apply power of a power rule: Apply the power of a power rule to the expression (y−(1)/(2))4. Using the rule, we multiply the exponents: −21×4.
Perform exponent multiplication: Perform the multiplication of the exponents. −21×4=−21×14=−24.
Simplify multiplication result: Simplify the result of the multiplication. −24 simplifies to −2.
Write final expression: Write the final expression using the simplified exponent.The expression (y−(21))4 simplifies to y−2.
