Select all irrational numbers.

Maurinko [17]

Answer:

OPTION A

OPTION B

OPTION C

Step-by-step explanation:

Irrational numbers are the subset of real numbers. Their decimal representation neither form a pattern nor terminate.

OPTION A: $\sqrt{\frac{1}{2}}$

This is equal to $\frac{1}{\sqrt{2}}$ .

$\sqrt{2} = 1.414...$ is non-terminating. So, it is an irrational number. Hence, the reciprocal of an irrational number would also be irrational. So, OPTION A is irrational.

OPTION B: $\sqrt{\frac{1}{8}}$

This is equal to $\frac{1}{2\sqrt{2}}$ . Using the same logic as Option A, we regard OPTION B to be irrational as well.

OPTION C: $\sqrt{\frac{1}{10}}$

This is equal to $\frac{1}{\sqrt{5}\sqrt{2}}$ .

Both $\sqrt{5}$ and $\sqrt{2}$ are irrational. So, the product and the reciprocal of the product is irrational as well. So, OPTION C is an irrational number.

OPTION D: $\sqrt{\frac{1}{16}}$

16 is a perfect square and is a rational number. $\frac{1}{\sqrt{16}}$ = $\frac{1}{4}$ . This is equal to 0.25, a terminating decimal. So, OPTION D is a rational number.

OPTION E: $\sqrt{\frac{1}{4}}$

4 is a perfect square as well. $\frac{1}{\sqrt{4}} = \frac{1}{2} = 0.5$ , a terminating decimal. So, OPTION E is a rational number.

What is -3/4 + 3/8? Thanks.

AURORKA [14]

Answer:

$- \frac{3}{8}$

Step-by-step explanation:

First, we change both denominators to the LCM (lowest common multiple) which is 8.

$- \frac{3}{4} + \frac{3}{8} = - \frac{6}{8} + \frac{3}{8}$

Since the denominators are the same, we can add the numerators.

$\frac{ - 6 + 3}{8}$

$\frac{ - 3}{8}$

or it can be written as

$- \frac{3}{8}$

Well first you have to figure out what 25* 16 is, 400 and then you have to find what mulitplies to get 400 and adds up to get 40 and when you find the answer to that then you just GCF it.
