18x[1+3^7x3^53+7^84:7^14+(5^4)^20]:(13^0+3^60+7^70+5^80)

Answer 1

Răspuns:

Explicație pas cu pas:

$18\cdot[1 +3^7\cdot 3^{53}+7^{84}:7^{14} + (5^4)^{20}] : (13^0 + 3^{60}+7^{70} + 5^{80}) =$

$=18\cdot(1 +3^{7+53}+7^{84-14} + 5^{4\cdot20} : (1 + 3^{60}+7^{70} + 5^{80}) =$

$=18\cdot(1 +3^{60}+7^{70} + 5^{80} : (1 + 3^{60}+7^{70} + 5^{80}) =$

$=1$
