Simplify coefficients: Simplify the coefficients and separate the variables.We have the expression (8x5y−1)/(4y8). First, we simplify the numerical coefficients by dividing 8 by 4.8/4=2Now we have 2x5y−1/y8.
Apply quotient rule: Apply the quotient rule for exponents. The quotient rule states that when we divide like bases, we subtract the exponents. For the variable x, we only have x5 in the numerator, so it remains as is. For the variable y, we have y−1 in the numerator and y8 in the denominator. We subtract the exponents: (−1)−8=−9. Now we have 2x5y−9.
Rewrite negative exponents: Rewrite negative exponents as positive exponents in the denominator. A negative exponent means that the base is on the wrong side of the fraction line, so we move y−9 to the denominator to make it a positive exponent. Now we have y92x5.
