Question

5003²-4997²??????????​

Answer 1

Answer:

Para facilitar o entendimento, chamarei 5000 = X

Sabemos que:

5003 = 5000 + 3 = X + 3

4997 = 5000 - 3 = X - 3

Assim:

5003×4997 = (X + 3)×(X - 3)

que resulta em:

x {}^{2} - {3}^{2} = {x}^{2} - 9x2−32=x2−9

assim ficamos com:

\begin{gathered}x = 5000 \\ {5000}^{2} - 9 = 25 \times {10}^{6} - 9\end{gathered}x=500050002−9=25×106−9

Answer 2

Answer:

Answer:

Commission = rate of commission x total sales

Rate of commission = Commission/Total sale

Since the rate of commission is same,

\begin{gathered} \frac{42560}{255360} = \frac{38500}{x} \\ x \: = \frac{38500 \times 255360}{42560} \\ x = 231000\end{gathered}

255360

42560

=

x

38500

x=

42560

38500×255360

x=231000
