Explicação passo a passo:
.
a) [ (- 3/4)-² + (1/10)-² ]² = [ (- 4/3)² + (10/1)² ] ²
. = [ 16/9 + 100/1 ]²
. = [ 16/9 + 900/9 ]²
. = [ 916/9 ]²
. = 916 . 916 / 9 . 9
. = 839.056/81
b) [ (1/2)^-3 + (1/4)-² ]² = [ (2/1)^3 + (4/1)² ]²
. = [ 8 + 16 ]²
. = 24²
. = 24 . 24
. = 576
c) [ - (- 1/3)^3 - (1/4)-² ]-² = [ - (- 1/27) - (4/1)² ]-²
. = [ + 1/27 - 16/1 ]-²
. = [ + 1/27 - 432/27 ]-²
. = [ - 431/27 ]-²
. = [ - 27/431 ]²
. = + 27 . 27 / 431 . 431
. = 729/185.761
d) [ (3/2 + 9/2)² + 3/5 ]-² = [ 12/2 + 3/5 ]-²
. = [ 60/10 + 6/10 ]-²
. = [ 66/10 ]-²
. = [ 33/5 ]-²
. = [ 5/33 ]²
. = 5 . 5 / 33 . 33
. = 25/1.089
