Answer 2

Explicație pas cu pas:

Buna !!

21) 45:5+54:6-(54+45):(4+5)=

=9+9-99:9=

=18-11=

=7✅

23) (8×5:10+6×6)-(10+3×3)=

=(40:10+36)-(10+9)=

=(4+36)-19=

=40-19=

=21✅

25) 33+9:3×10-(60:10×4-20)=

=33+3×10-(6×4-20)=

=33+30-(24-20)=

=63-4=

=59✅

27) 99-(13+6×5-8:4)+5×5=

=99-(13+30-2)+25=

=99-(43-2)+25=

=99-41+25=

=58+25=

=83✅

29) 63+3×4-(2×2×2×2:8+5×6)=

=63+12-(4×2×2:8+30)=

=75-(8×2:8+30)=

=75-(16:8+30)=

=75-(2+30)=

=75-32=

=43✅

Succes !!;)
