Odpowiedź:
[tex]a = 4^{2} * 5^{3} * \frac{1}{2}^{2} = 16 * 125 * \frac{1}{4} = 500[/tex]
0,04a = 0,04 * 500 = 20

Szczegółowe wyjaśnienie:
Procenty
1% = 1/100 = 0,01
[tex]a = 4^{2}\cdot5^{3}\cdot(\frac{1}{2})^{2}=(4\cdot\frac{1}{2})^{2}\cdot5^{3} = 2^{2}\cdot125 = 4\cdot125 = \underline{500}\\\\4\% = \frac{4}{100} = 0,04\\\\4\% \ liczby \ a = 0,04\cdot500 = \boxed{20}[/tex]
