Answer:

\frac{1}{2^{n} }

Step-by-step explanation:

The rules of exponents state that

a^{-m} = \frac{1}{a^{m} } and a^{0} = 1

Thus

2^{-5} = \frac{1}{2^{5} } = \frac{1}{32}

2^{-4} = \frac{1}{2^{4} } = \frac{1}{16}

2^{-3} = \frac{1}{2^{3} } = \frac{1}{8}

and so on , to

2^{0} = 1

Question 11 (5 points)
KATRIN_1 [288]

Answer:

Yes

Step-by-step explanation:

Substitute the x value in the ordered pair for the x in the equation, or 2, and the y-value (6) in for y. So, 2 + 6 = 8, and this is true. Then do 3(2) - 6 = 0, which is also true.

Least to greatest 0.2,4/15,0.21,1/4
vladimir1956 [14]

Turn all rational numbers into fractions:

0.2 remains as it is

4/15 as a decimal is 0.26 with the 6 repeating

0.21 remains as it is

1/4 as a decimal is 0.25

Now we can organize from least to greatest as shown below:

0.2, 0.21, 0.25 (1/4), 0.2666666 (4/15)

Hope this helped!
