Match the following items by evaluating the expression for x = -2.

solong [7]

Answer:

see below

Step-by-step explanation:

x^-2 = 1/x^2 Let x = -2 1/ (-2)^2 = 1/4

x^-1 = 1/x^1 Let x = -2 1/ (-2)^1 = 1/(-2) = -1/2

x^0 = 1

x^1 = x Let x = -2 (-2)

x^2 = Let x = -2 (-2)^2 = 4

Can someone help me with this please?

qwelly [4]

Answer:

see below

Step-by-step explanation:

The applicable properties of exponents are ...

(a^b)^c = a^(bc)

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

$(-2^2)^{-6}\div(2^{-5})^{-4}=2^{-12}\div2^{20}=2^{-12-20}=\boxed{2^{-32}}\\\\2^4\cdot(2^2)^{-2}=2^{4+2(-2)}=2^0=\boxed{1}\\\\(2^2)^2\cdot (2^3)^{-3}=2^{2(2)+3(-3)}=2^{4-9}= \boxed{2^{-5}}\\\\(-2^{-4})^{-2}\cdot(2^2)^0=2^{(-4)(-2)}\cdot 1= \boxed{2^8}$

Please note that ...

$(-2^2)^{-6}=\dfrac{1}{(-4)^6}=\dfrac{1}{4096}=2^{-12}$

That is, since the outside exponent is even, the sign is immaterial. This is also true for the other expression containing -2. The result is positive.
