no 10 bagaimana caranya

10.

2/5 × 3/8[^1/2] × 2/5 [ ^ 1/4×1/2]
---------------------------------------------
2/5[^3/16]

6/40[^1/2] × 2/5 [^1/8]
-------------------------------
2/5[^1/8]

= 6/40[^1/2]
= 0,3
= 3/10
= 2/5^1/4

Jawabannya:

((2/5)3/8)^½ × ((2/5)^1/4)^1/2 / (2/5)^3/16
= (2/5)×(3/8)^1/2 × (2/5)^1/4×1/2 /(2/5)^3/16
= (6/40)^1/2 × (2/5)^1/8 /(2/5)^1/8
= (6/40)^1/2
= ((2/5)1/4 → Opsi A
