8 Identifică valoarea numerelor a, b şi c şi efectuează exerciţiile din casete. axb+c a = 371 x 1 x 125-427 x (325-279); b = 534 x 149-(527+1 459-366) x 0; c = 1000 x 100-425 x 18 - 145 x 45. ax(b + c) (b-a) xc​

Answer 1

Răspuns:

$a = 371*1*125-427*(325-279)\\\\a=46375-427*46\\\\a=46375-19642= > a=26733\\\\b = 534*149-(527+1 459-366)*0\\\\b=79566-0= > b=79566\\\\c=1000*100-425*18-145*45\\\\c=100000-7650-6525= > c=85825\\\\a*(b + c)=26733*(79566+85825)=26733*165391=4421397603\\\\a*b+c=26733*79566+85825=2127037878+85825=2127123703\\\\(b-a)*c=(79566-26733)*85825=52833*85825=4534392225$

Answer 2

a=371×1×125-427×(325-279)

a=371×1×125-427×46

a=371×125-19.596

a=46.375-19.596

a=26.780

b=534×149-(527+1459-366)×0

b=534×149-0

b=79.556

c=1000×100-425×18-145×45=

c=100.000-7.650-6.525

c=85.825

a×b+c=

26.780×79.556+85.825

=2.130.509.680+85.825

=2.130.595.505

a×(b+c)=

26.780×6.827.893.700

=182.850.993.286.000

(b-a)×c=

=52.776×85.825

=4.529.500.200
