Answer:
(5r⁷s⁹)² = 25r^14s^18
To simplify, we square both the coefficients and multiply the exponents of the variables.
(1/4g³v⁶)² = 1/16g^6v^12
To simplify, we square the fraction and multiply the exponents of the variables.
[(2/3s³h)³•h²]/s = [(8/27)s^9h^2]/s = (8/27)s^8h^2
To simplify, we distribute the exponent of the numerator to both variables, and cancel the s in the denominator.
