P(z≤2.75)=0.997
thus
1-P(z≤2.75)

Answer: 2^{30}

Step-by-step explanation:

In order to solve this exercise it is important to remember:

1. The Negative exponent rule, which states that:

a^{-n}=\frac{1}{a^n}

2. The Product of powers property, which states that:

(a^m)(a^n)=a^{(m+n)}

Therefore, knowing the explained above and having the following expression provided in the exercise:

\frac{2^{14}}{2^{-16}}

You can identify that the numerator and the denominator have the same base 2. Then, you can simplify the expresssion as following:

(2^{14})(2^{16})=2^{(14+16)}=2^{30}
