2  to the power of   21 . Cancel the common factor of  32. Combine  125  and  1 /65536

Answer 2

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.
