A = 2 ² x 1 x 2 ⁸ x 2 ⁻³
A = 2 ⁷ x 1
= 2 ⁷
B = 10 ² x 8 / 10 ² x 2 x 10
B = 8 x 10 ² / 20 x 10 ²
b = 0.4 x 10 ⁰
B = 0.4 x 1 = 0.4
C = ( 0.5 ²⁵)⁵ x 0.5 ⁻¹
= 0.5 ¹²⁵ x 0.5 ⁻¹
= 0.5 ¹²⁴
D = ( 11 x 2 ) ⁴ / 11 ³ x 11 ⁻¹
= 11 ⁴ x 2 ⁴ / 11 ²
= 11 ² x 2 ⁴
12 ^0.5 x 12 ^2.5 / 12 ^0.5
= 12 ^1.25 /12 ^0.5
= 12 ^0.75
