Question

0,2(-5)^2-(1/2)^4*16

Answer 1

0,2(-5)^2-(1/2)^4*16=1-0.0625×16=15

Answer 2

Let's break down the expression step by step:

1. First, we need to evaluate the exponentials: -5^2 = (-5) * (-5) = 25 (1/2)^4 = (1/2) * (1/2) * (1/2) * (1/2) = 1/16

2. Next, we multiply the results of the exponentials with the constants: 0.2 * 25 = 5 1/16 * 16 = 1

3. Finally, we subtract the results: 5 - 1 = 4

So, the final value of the expression is 4.
