Penjelasan dengan langkah-langkah:

1.

a. 2⁶ = 2 × 2 × 2 × 2 × 2 × 2

b. (2/3)⁴ = 2/3 × 2/3 × 2/3 × 2/3

 

2.

a. (-5)^3×(-5)^-2

= (-5)³+-²

= -5¹

 

b. 18a^8:6a^5

= 18a⁸ ÷ 6a⁵

= 18÷6. a⁸-⁵

= 3a³

 

3.

a. (2/3)^-³

= (3/2)³

= 27/8

 

b. (1/3)^5×(1/3^7)

= 1/243 × 1/2187

= 1/531.441

 

4.

a. 0.00005|6

= 5,6 × 10⁵

 

b. 350×10^-5

= 3,5 × 10² × 10-⁵

= 3,5 × 10-³

 

5.

a. 3,25×10^5

= 325.000

 

b.3,75×10^-5

= 0,0000375

 

7.

2³ : 8³

8 : 512

1 : 64
