Объяснение:

1) 10³-5²:8+(2/3)⁵×81=1000-25:8+(32/243)×81=1000-3.125+96=1092.875

2) 2.43×(1/3)³+6²(2⁵-28)=2.43×(1/27)+

36(32-28)=0.09+36×4=0.09+144=144.09

3) 9³-15²:16+(3/4)⁴:(27/32)=729-225:16+(81/256):(27/32)=729-14.0625+0.375=715.3125

4) (7²-51)³×(5/9)+3.6:9²=(49-51)³×(5/9)+3.6:81= -2³×(5/9)+(2/45)= -8×(5/9)+(2/45)= -4+(4/9)+(2/45)= -4+(22/45)
