Question

Comparați numerele x şi y, dacă x=8487:69-11^2+21•54-
5•(2026^1 - 45^2) și
y=563•12-6750+42•27:18+7^10• 7^9:(7^8)^2 dau coroana

Answer 1

Hei! :)

$x=8487:69-11^{2} +21*54-5*(2026^{1} -45^{2} )\\x=123-121+1134-5*(2026-2025)\\x=2+1134-5\\x=1136-5=1131\\\\y=563*12-6750+42*27:18+7^{10} *7^{9} :(7^{8} )^{2} \\y=6756-6750+1134:18+7^{19}:7^{16} \\y=6+63+7^{3} \\y=69+343\\y=412\\\\=> y<x$
