Question

calculati b) 8+2×[2⁶:4²+2³:(16²:8²-64:2⁵)] dau coroană ​

Answer 1

$8+2*[(2^{6}:4^{2} +2^{3}:(16^{2} :8^{2}-64:2^{5})]=\\8+2*[2^{6}:2^{4}+2^{2}:(2^{8}:2^{6}-2^{6}:2^{5})]=\\8+2*[2^{2}+2^{2}:(2^{2}-2)]=\\8+2*[4+2^{2}:(4-2)]=\\8+2*(4+2^{2})= \\8+2*6 = \\8+12 = 20$

Soluția ecuației este 20.
