What is the value of 7 ^−3 ^ −1 for = −2 and = 4?
andrey2020 [161]

Answer:

d. −7/32

Step-by-step explanation:

The expression that we have to evaluate in this problem is:

7x^{-3}y^{-1}

We have to evaluate this expression for:

x = -2

y = 4

We start by rewriting the expression by rewriting it using the following:

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

So the expression can be rewritten as

7x^{-3}y^{-1}=\frac{7}{x^3 y}

Now we observe that:

(-2)^3=(-2)(-2)(-2)=-8

Therefore, by substituting x = -2 and y = 4 into the expression, we find:

\frac{7}{(-2)^3\cdot 4}=\frac{7}{-8\cdot 4}=-\frac{7}{32}

Select all the numbers that are rational.
anygoal [31]

Answers:

C, D, E

Step-by-step explanation:

A rational number is a integer. It is also a terminating or repeating decimal.

A rational number can be written as a fraction of two integers.

Answer A is not correct because it's decimal never ends. It is also not repeating. A cannot be written as a fraction.

Answer B is not correct because the square root is not a whole number, or a perfect square. The square root has a non-terminating and non-repeating decimal, just like A. B cannot be written as a fraction.

Answer C is rational because it has a terminating decimal.

D and E are integers, which also can be written as fractions.

Out of the options given, C, D, and E have rational numbers, while all others do not.

The answers are C, D, and E.
