Answer:
To find the product of (7x²y³) and (3x⁵,⁸), we multiply the coefficients and add the exponents of the variables:
Product = (7 * 3) * (x² * x⁵) * (y³ * y⁰,⁸)
Simplifying further:
Product = 21x⁷ * y³ * y⁰,⁸
Since y⁰,⁸ is equal to 1 (any variable raised to the power of 0 is 1), we can simplify it:
Product = 21x⁷ * y³ * 1
Finally, we can rewrite the product as:
Product = 21x⁷ * y³
Therefore, the correct answer is O) 21x⁷y³.
