Q. Express the following fraction in simplest form using only positive exponents.4z52(z5)2Answer:
Apply Power Rule: Simplify the numerator by applying the power of a power rule.The power of a power rule states that (am)n=am∗n. Therefore, we can simplify the numerator as follows:(2(z5)2)=2×(z5∗2)=2×z10
Divide Numerator and Denominator: Simplify the fraction by dividing the numerator by the denominator.We have the fraction (2⋅z10)/(4z5). To simplify, we divide both the coefficients and the like terms with exponents.(2⋅z10)/(4z5)=(2/4)⋅(z10−5)
Simplify Coefficients and Exponents: Simplify the coefficients and subtract the exponents.Simplifying the coefficients 42 gives us 21. Subtracting the exponents gives us z(10−5)=z5.So, $(\frac{\(2\)}{\(4\)}) \cdot (z^{(\(10\)\(-5\))}) = (\frac{\(1\)}{\(2\)}) \cdot z^\(5\)
Write Final Expression: Write the final simplified expression.\(\newline\)The final simplified expression is \((\frac{1}{2}) \times z^5\), which can also be written as \(\frac{z^5}{2}\).
