Question

10^2*0,63-5^2*0,008+4,44

Answer 1

Ответ:

67,24

Пошаговое объяснение:

Вычислить

$10^{2} \cdot 0,63 -5^{2} \cdot 0,008+4,44$

Квадратом числа a называется произведение двух множителей, каждое из которых а.

$10^{2} =10\cdot 10=100;\\5^{2} =5\cdot5=25$

$10^{2} \cdot 0,63 -5^{2} \cdot 0,008+4,44=100\cdot 0,63-25\cdot0,008 +4,44=\\\\=63-0,2+4,44 =67,44-0,2=67,24$

$\displaystyle \begin{array}{r}\underline{\times\begin{array}{r}25 \\ 0\text{,}008\end{array}} \\ 0\text{,}200 \hspace{6pt} \end{array}$     $\begin{array}{r} \underline {+ \begin{array}{r} 63,00 \\ 4,44 \end{array} } \\ \begin{array}{r} 67,44 \end{array} \end{array}$    $\begin{array}{r} \underline {- \begin{array}{r} 67,44 \\ 0,20 \end{array} } \\ \begin{array}{r} 67,24 \end{array} \end{array}$

Answer 2

Let's break down the expression step by step:

1. $10^2 = 100$
2. $5^2 = 25$

Now substitute these values back into the original expression:

$100 \times 0.63 - 25 \times 0.008 + 4.44$

Calculating each part of the expression:

1. $100 \times 0.63 = 63$
2. $25 \times 0.008 = 0.2$

Now the expression becomes:

$63 - 0.2 + 4.44$

Finally, add the remaining numbers:

$63 - 0.2 + 4.44 = 67.24$

So, $10^2 \times 0.63 - 5^2 \times 0.008 + 4.44 = 67.24$.
