Q. Simplify. Express your answer as a single fraction in simplest form. \newline4y5z42\frac{4}{y^5} - \frac{z^4}{2}
  1. Find LCM: Find the least common multiple (LCM) of the denominators y5y^5 and 22. Since y5y^5 and 22 have no common factors other than 11, the LCM is simply the product of the two, which is 2y52y^5.
  2. Make denominators same: Make the denominators the same by multiplying the first fraction by 22\frac{2}{2} and the second fraction by y5y5\frac{y^5}{y^5}. This gives us 4×2y5×2z4×y52×y5\frac{4\times 2}{y^5\times 2} - \frac{z^4\times y^5}{2\times y^5}.
  3. Perform multiplications: Perform the multiplications in the numerators and denominators. This results in 8y5z4y52y5.\frac{8}{y^5} - \frac{z^4y^5}{2y^5}.
  4. Combine fractions: Since the denominators are now the same, we can combine the fractions. This gives us (8z4y5)/2y5(8 - z^4y^5)/2y^5.
  5. Check for simplification: Check if the expression can be simplified further. Since 88 and z4y5z^4y^5 have no common factors, and the denominator 2y52y^5 is already in simplest form, the expression cannot be simplified further.
