Answer:
256
Step-by-step explanation:
A calculator works well for this.
_____
None of the minus signs are subject to the exponents (because they are not in parentheses, as (-1)^5, for example. Since there are an even number of them in the product, their product is +1 and they can be ignored.
1 to any power is still 1, so the factors (1^n) can be ignored.
After you ignore all of the things that can be ignored, your problem simplifies to ...
(2^2)(2^-3)^-2
The rules of exponents applicable to this are ...
(a^b)^c = a^(b·c)
(a^b)(a^c) = a^(b+c)
Then your product simplifies to ...
(2^2)(2^((-3)(-2)) = (2^2)(2^6)
= 2^(2+6)
= 2^8 = 256
Answer:
27
Question:
Find so that
is a solution to
.
Step-by-step explanation:
So we are asked to replace with -14 and solve for
in the equation:
.
with
:
Add 42 on both sides:
Divide both sides by 2:
.
So the -coordinate that corresponding to
is
.
Verify that:
is a point satisfying
.
Replace with 27 and
with -14:
is true so our work must be right.
