Q. Select the equivalent expression.(nn−5)2454n515n44n55n41
Simplify base: Simplify the base of the expression.We have the expression ((n−5)/(n))(5)/(24). To simplify the base, we need to apply the exponent rule am/an=a(m−n).So, n−5/n=n(−5−1)=n−6.
Apply exponent: Apply the simplified base to the exponent.Now we have (n−6)(5/24). According to the power of a power rule, (am)n=am∗n, we multiply the exponents.So, (n−6)(5/24)=n(−6)∗(5/24)=n−5/4.
Rewrite with positive exponent: Rewrite the expression with a positive exponent.The expression n(−5/4) can be rewritten with a positive exponent by taking the reciprocal of the base.So, n(−5/4)=n(5/4)1.
Convert to radical: Convert the exponent to a radical.The expression n451 can be rewritten as a radical, where the denominator of the exponent becomes the index of the root.So, n451=4n51.
Compare with options: Compare the result with the given options.The expression we have found, 1/4n5, matches the second option: (1)/(4n5).
