Set it up as a proportion. start with the smaller numbers, 6 ft friend and 4 ft shadow. 4/6 reduces to 2/3.  so 2/3= 24/x.   the easiest way to finish the problem is to divide by 2, and multiply by 3. for instance- 24/2= 12. 12*3= 36, so the building is 36 feet tall. to check plug it back in, is 2/3= 24/36?

((-2^2)(-1^-3))•((-2^-3)(-1^5))^-2
Vitek1552 [10]

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
