Question

calculați: 3•{2•3^2+30^2:6^2+2•[2^4•3-(2^16•3^16)^2:(2^15)^2:3^30+3•5^2]}​

Answer 1

Răspuns:

Explicație pas cu pas:

$=3[2*9+5^{2} +2[16*3-(2^{16} *3^{16})^{2} /2^{30} *\frac{1}{3^{30} }+3*25]] \\=3[18+25+2(48-\frac{2^{16}*3^{16} }{2^{30} } *\frac{1}{3^{30} }+75)]\\ =3[18+25+2(48-\frac{6^{32} }{2^{30} } *\frac{1}{3^{30} }+75)]\\\\ =3{18+25+2(48-3^{2} *2^{2} +75)]\\=3[18+25+2(48-6^{2} +75)]\\\\=651$
