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:
Step-by-step explanation:
If we are given angles B and C, then all we have to do is add them together and then subtract that from 180 since all the angles of a triangle have to add up to equal 180.
62 + 48 = 110
180 - 110 = 70
Angle A = 70°
Answer: 14,15,29...................
1) order the numbers from smallest to largest
67, 76, 76, 82, 84, 87, 93
2) the middle number is the median as there are an odd number which makes it easier.
The median is 82.
1. Consider the pyramid ABCDE in the figure 1 attached:
Each side of the square base equals
(units)
Area of 1 lateral side of pyramid ABCDE is
so the total lateral area is
(units squared)
and the total surface area is
(units squared)
2. Now consider the second figure KLMNP, Sydney's pyramid:
The lateral area is
so the total area of the second pyramid is
So 2 things can be said about the areas:
i) the lateral area of Sydney's pyramid is
times larger than the lateral area of the original pyramid.
ii) The total area of Sydney's pyramid is
units squared larger than the total area of the original pyramid.
