a) a = 2
= 8⁻² · 16 ³=
= ( 2³)⁻²* (2⁴)³ =
= 2⁻⁶* 2¹² =
= 2⁶=
= a⁶
b) a = ¾
(¾)²⁰ · (¾)¹⁰=
=(¾)³⁰=
= a³⁰
c) a = ⅘
( 1 ¼) ⁻⁴=
= (5/4)⁻⁴=
= (4/5)⁴=
= a⁴
d) a = 5/3
(0,6)⁻ ⁴=
= (6/10)⁻⁴ =
= (3/5)⁻⁴ =
= (5/3)⁴ =
= a⁴
e) a = 2
4⁸ ·32²/ 64³=
= (2²)⁸ *(2⁵)² / (2⁶)³ =
= 2¹⁶ * 2¹⁰ / 2¹⁸ =
= 2²⁶/ 2¹⁸ =
= 2⁸ =
= a⁸
f) a = 3
27⁵ : 81⁴/ 9³
= (3³)⁵ : (3⁴)⁴/ (3²)³ =
= 3¹⁵: 3¹⁶/ 3⁶ =
= 3⁻¹ / 3⁶ =
= 3⁻⁷=
= a⁻⁷
