Question

63,02-(-0,4)-(- 1/2)+ 0,2²=

Answer 1

Ответ:

$=63.96$

объяснение:

$63.02-\left(-0.4\right)-\left(\frac{-1}{2}\right)+0.2^2$

$=63.02+0.4-\frac{-1}{2}+0.2^2$

$=63.02+0.4-\left(-\frac{1}{2}\right)+0.2^2$

$=63.02+0.4+\frac{1}{2}+0.2^2$

$=\frac{1}{2}+0.2^2+63.42$

$=\frac{1}{2}+0.04+63.42$

$=\frac{1}{2}+63.46$

$=0.5+63.46$

$=63.96$

Answer 2

Let's break down the expression step by step:

1. 63,02 - (-0,4) = 63,02 + 0,4 = 63,42
2. Now, we have 63,42 - (-1/2). When you subtract a negative number, it's the same as adding its positive counterpart, so this becomes: 63,42 + 1/2 = 63,92 + 0.5 = 64,42
3. Finally, 0,2² means 0,2 raised to the power of 2: 0,2² = 0,2 * 0,2 = 0,04

Now, add this result to the previous one:

64,42 + 0,04 = 64,46

So, the final result of the expression is 64,46.
