Calculati 2^7-11•{91-5[22-5•(40^2-41•39)]}+(3^2-2^3)^2017Dau coroana

Answer 1

$7^{2} -11*(91-5[22-5*( 40^{2}-41*39)])+( 3^{2} -2 ^{3} ) ^{2017} =$$128 -11*(91-5[22-5*( 40^{2}-1599)])+( 9 -8 ) ^{2017} =$$128 -11*(91-5[22-5* 40^{2}-7995])+1 ^{2017}=$$128 -11*(91-5[8017-5* 40^{2}])+1 =$$128 -11*(91-40085+25* 40^{2})+1=$$128 -11*(-39994+25* 40^{2})+1=128 +439934-275* 40^{2}+1=$$440063-275*1600=440063-440000=63$
