Resolvendo...
0,2 - 10 - 1/4 + 10 = (10 e -10 se anulam)
1/5 - 1/4 = 4/20 - 5/20 = -1/20

0,2 - 1/(0,1) - 1/4 + 10 =>
0,2 - 10 - 0,25 +10 =>
0,2 - 0,25 = - 0,05

0,2 = 2/10
0,1 = 1/10
100 = 10²
Assim,
(2/10) - (1/10)ˉ¹ - (2)ˉ² + √10²
(2/10) - (10)¹ - (1/2)² + 10
(2/10) - 10 - (1/4) + 10
(2/10) - (1/4)
Mínimo Múltiplo Comum (mmc) entre 4,10 é 20, então:
(2.2 - 5)/20
(4 - 5)/20
- 1/20
ou
- 0,05
ou
- 5/100 = - 5%

0,2 – (0,1)˹ - 2ֿ² + â100 =
2/10 - (1/10)˹ - (2/1)ֿ² + 10 =
2/10 - 10/1 - (1/2)² + 10 =
tirando o mmc, teremos base 20 logo ficara.
4/20 - 200/20 - 5/20 + 200/20 =
(4-200-5=200)/20 =
-1/20 =
-0,05
0,2 = 2/10
(0,1)˹ = (1/10)˹ = 10/1
2˲=(2/1)˲ = (1/2)² = 1/4
â100 = 10
Resultado = -0,05

= 0,2- 1/0,1- 1/4+100^1/2=
0,2 - 10- 1/4 +10= 1/5-1/4= -1/20 ;)
