Question

can someone check my answer?

Answer 1

my answer was |-4*-2-8|+|-1-(-2^2)|+2*-2^3
| 0|+|-1-(-4)|+2-8
0+5+-6=-1

Answer 2

=−13

Answer 3

|(−4)(−2)−8|+|−1−(−22)|+2(−23)
=|8−8|+|−1−(−22)|+2(−23)
=|0|+|−1−(−22)|+2(−23)
=0+|−1−(−22)|+2(−23)
=0+|−1−(−4)|+2(−23)
=0+|3|+2(−23)
=0+3+2(−23)
=3+2(−23)
=3+(2)(−8)
=3+−16
=−13
