Answer 1

Răspuns:

sall

Explicație pas cu pas:

3-3³:(2-2-2-2³-2²-2¹-2%)=

3-3³:(2-2-2-8-4-2-0,02)=

3-3³:(0--6-2-0,02)=

3-3³(-6-1,98)=

3-3³--4,02=

3-27--4,02=

24--4,02=19,98

2×2²×2²:12+2+22²:(2²²-2²-2)=

2×2²×2²:12+2+22²:(4.194.304-4-2)=

2×2²×2²:12+2+22²:4194298=

2×4×4:12+2+484:4195298=

8×0,3+2+8667,9=

2,4+8669,9=8672,3

(57+5+55):5³+97:3=

(57+60):5³+97:3=

117:125+97:3=

0,9+32,3=33,2

3²+(4-6)²+25×5²-1=

3²+-2²+25×5²-1=

6+-4+25×25-1=

6+-4+625-1=

2+625-1=

627-1=626
