Answer:

The prime number 2.

Step-by-step explanation:

Odd number + Odd number = Even number

An odd number plus another odd number equals an even number. And most prime numbers are odd, so you might think this is true. Is it?

Wrong. The prime number 2 is an even number and

Even number + Odd number = Odd number

Odd number + Even number = Odd number

So, there is a number that can make the sum of two prime numbers odd.

Answer:

1. $(-2^2)^{-6}$ ÷ $(2^{-5})^{-4} \implies 2^{-32}$

2. $2^4 . (2^2)^{-2} \implies 1$

3. $(-2^{-4}).(2^2)^0 \implies -2^8$

4. $(2^2).(2^3)^{-3} \implies 2^{-5}$

Step-by-step explanation:

1. $(-2^2)^{-6}$ ÷ $(2^{-5})^{-4}$ :

$= \frac{ ( - 2 ^ 2 ) ^ { - 6 } } { ( 2 ^ { - 5 } ) ^ { - 4 } } = \frac{2^{-12}}{2^{20}} = 2^{-12-20}=2^{-32}$

2. $2 ^ 4 . ( 2 ^ 2 ) ^ { - 2 }$ :

$= 2^4 \times \frac{1}{2^4} = 1$

3. $(-2^{-4}).(2^2)^0$ :

$= (-2^4)^2 \times 1 = -2^8$

4. $(2^2).(2^3)^{-3}$ :

$= 2^4 \times \frac{1}{2^9} =\frac{1}{2^5} =2^{-5}$

Han's house is 450 meters from school. Lin’s house is 135 meters closer to school. How far is Lin’s house from school?

Marina86 [1]

Solution:

Note that:

Han's house = 450 m from school
Lin's house = (450 - 135) from school

Looking at the options, we can tell that the letter "z" represents Lin.

=> z = (450 - 135)
=> z = 450 - 135

This option matches with Option D.

Option D is correct.
