Mapel : Matematika
Kelas : IX SMP
Bab : Eksponen

Pembahasan :
(5/4)¯² . 2¯¹ + 105° - (1/2)²
= (4/5)² . 1/2 + 1 - 1/4
= 16/25 . 1/2 + 1 - 1/4
= 8/25 + 1 - 1/4
= (32 + 100 - 25)/100
= 107/100

5/4^(-2) × 2^(-1) + 105^0 - (1/2)^2
= 5/(1/4)^2 × (1/2)^1 + 105^0 - (1/2)^2
= 5/(1/16) × (1/2) + 1 - 1/4
= 5 × 16/1 × 1/2 + 4/4 - 1/4
= 80/2 + 3/4
= 40 + 3/4
= 40 3/4
