Answer 1

Răspuns:

8+5•[20+3•(2+4•6)-15]-3=?

8+5•[20+3•(2+24)-15]-3=8+5•(20+3•26-15)-3=8+5•(20+78-15)-3=8+5•(98-15)-3=8+5•83-3=8+415-3=423-3=420

R=420

[150+12•8-(142-40:4)]•10=[150+12•8-(142-10)]•10=(150+12•8-132)•10=(150+96-132)•10=114•10=1140

R=1140

5+5•[5+2•(5+25•1-24:4)]=5+5•[5+2•(5+25-6)]=(5+5•24)=5+120=125

R=125
