Answer:

Equation is incorrect

Answer (If you did the math):

1000 = 4000/2^21 or 1000 = 125/65536

Step-by-step explanation #1:

1. We know that 1000 is equal to 4000 * 1/4, meaning that the parenthesis is equal to 1/4. 1/4 is 2^-2 (Look below), and since 2^-21 does not equal 2^-2, so this equation is incorrect.

In a situation where:


y^(- x) and -x is negative ------>
y^(-x) = 1/y^(x) (And Vice Versa)

Step-by-step explanation #2 (If you did the math):

Open the parenthesis and make the 2^-21 into a fraction. This would be 1/2^21, which you would then multiply by 4000 to get 4000/2^21. You can now use a fraction calculator to calculate this value in fraction. 4000/2^21 simplifies to 125/65536.
