a) [(120•625)•(2³•10)]:(2•5³:25)⁵=60
= [75.000•(2•2•2•10)]:(2•5•5•5:25)⁵
= [75.000•(8•10)]:(2•125:25)⁵
= (75.000•80):(250:25)⁵
= 6.000.000:10⁵
= 6.000.000:10•10•10•10•10
= 6.000.000:100.000.
= 60
b) 6+2•[(3•5²-2²•18:3²+3•11):2²]=56
= 6+2•[(3•5•5-2•2•18:3•3+33):2•2]
= 6+2•[(3•25-4•18:9+33):5]
= 6+2•[(75-72:9+33):4]
= 6+2•[(75-8+33):4]
= 6+2•[(67+34):4]
= 6+2•(100:4)
= 6+2•25
= 6+50
= 56
Sper că te-am ajutat!
