Answer 1

1) а³¹=а¹⁹•а*

31-19=12

а³¹=а¹⁹•а¹²

2) (-d)⁵²=(-d)³⁴•(-d)*

52-34= 18

(-d)⁵²=(-d)³⁴•(-d)¹⁸

3)(k/3)²⁰=(k/3)¹⁰•(k/3)*

20-10=10

(k/3)²⁰=(k/3)¹⁰•(k/3)¹⁰

4)b²⁴=b*•b¹⁶

24-16=8

b²⁴=b⁸•b¹⁶

5)(xy)⁹=(xy)³•(xy)*

9-3=6

(xy)⁹=(xy)³•(xy)⁶

6)(1,3t)*:(1,3t)⁸=(1,3t)¹³

13+8=21

(1,3t)²¹:(1,3t)⁸=(1,3t)¹³
