Answer 1

Răspuns:

• $\bf \red{a = 5}$
• $\bf \green{b = 3}$
• $\bf \blue{c=7}$
• $\bf \purple{d=4}$

Explicație pas cu pas:

$\bf \overline{a3c4} = 5\cdot1000 + b\cdot100 + 7\cdot10 +d$

$\bf Descompunem ~in ~baza ~zece~ numarul~ \overline{a3c4}$

$\bf \overline{a3c4} = a\cdot1000 + 3\cdot100 + c\cdot10 +4\cdot1$

$\bf \red{\underline{a}}\cdot1000 + \green{\underline{3}}\cdot100 + \blue{\underline{c}}\cdot10 +\purple{\underline{4}}\cdot1 = \red{\underline{5}}\cdot1000 + \green{\underline{b}}\cdot100 + \blue{\underline{7}}\cdot10 +\purple{\underline{d}}$

$\implies \bf \red{\underline{a = 5}}$

$\bf\implies \green{\underline{b = 3}}$

$\bf \implies \blue{\underline{c=7}}$

$\bf \implies \purple{\underline{d=4}}$

Answer 2

$\it \overline{a3c4}=a\cdot1000+3\cdot100+c\cdot10+4\\ \\ \overline{a3c4}=5\cdot1000+b\cdot100+7\cdot10+d\\ \rule{160}{0.3}\\ a=5;\ b=3;\ c=7;\ d=4$
