Final answer:
To simplify the expression (9h³)(5h²), you can multiply the coefficients and add the exponents of the variables. The simplified expression is 45h⁵.
Step-by-step explanation:
To simplify the expression (9h³)(5h²), you can multiply the coefficients and add the exponents of the variables. In this case, 9 multiplied by 5 equals 45. The variable 'h' has an exponent of 3 in the first expression and 2 in the second expression, so you add the exponents to get a total exponent of 5. Therefore, the simplified expression is 45h⁵.
