Пошаговое объяснение:

1.

(7+4)³=11³=1331

5²+4²=25+16=41

(10²-2⁶)÷6+1¹⁰=(100-64)/6 +1=36/6 +1=6+1=7

3²·19²·5³=(3·19·5)²·5=285²·5=81225·5=406125

2.

(y-35)+12=32; y-35=32-12; y=20+35=55

124÷(y-5)=31; y-5=124/31; y=4+5=9

3.

21/30 +60/30 +9/30=(21+60+9)/30=90/30=3

(82/144 -36/144)+118/144=(82-36+118)/144=164/144=41/36=1 5/36

26/121 -(13/121 +12/121)=(26-25)/121=1/121

1/2 +3/2 +4/2 +5/2 +6/2 +7/2=(1+3+4+5+6+7)/2=26/2=13
