Question

Calculati; a :4+bx2+10xc stiind ca:
a=183-(172+160):4+25x(5x3-15)
b=25+3x[21-(7-7):2]:9
c=[(20+4):6-4]x35+2x(5x15-2x3x5)
 va rog frumos cat de repede 
multumesc mult mult

Answer 1

a=183-(172+160):4+25x(5x3-15)=183-332:4+25x(15-15)=183-83+25x0=183-83+0=183-83=100
b=25+3x[21-(7-7):2]:9=25+3x[21-0:2]:9=25+3x[21-0]:9=25+3x21:9=25+63:9=25+7=32


c=[(20+4):6-4]x35+2x(5x15-2x3x5)=[24:6-4]x35+2x(75-30)=[4-4]x35+2x45=0x35+90=0+90=90



a :4+bx2+10xc=100:4+32x2+10x90=25+64+900=989

Answer 2

a=183-332:4+0
a=183-83+0
a=100
b=25+3x21:9
b=25+63:9
b=25+7
b=32
c=0+2x(75-30)
c=0+2x45
c=90
a:4+bx2+10xc=
100:4+32x2+10x90=
25+64+900=
87+900=987
