The sample size n = 1200
The sample proportion of those that will vote for the Republican candidate is represented by
The null and the alternative hypothesis can be computed as:
The formula for the one-sample Z-test for the population proportion can be expressed as:

We are asked to simplify the given mathematical expression a5*3b9*6a. To do this, we need to follow the law of exponent that if it is same variable being multiplied we can add the power. In this problem, variable "a" existed twice so we can add powers of a5 to 6a such as:
6a(5+1) *3b9
6a6*3b9 , then multiply constants which are 6 and 3
18a6b9
The answer is 18(a^6)(b^9).
Acres of planted corn = (2/7) * (4/5)
= (2/7) * .8 = 1.6 / 7 acres = 0.2285714286 acres
