Question

Resolva:

b) 4⁰ + 2¹ - 1⁸

c) (20/3)^⁻3

d) 8⁵.8⁻⁶

e) 9⁻¹⁰ : 9⁻⁸

Answer 1

b)

4^0 + 2¹ - 1^8 =
1 + 2 - 1 =
2

c)

(20/3)^-3 =
(3/20)³ =
27/8000

d)

8^5.8-6 =
8^-1 =
1/8

e)

9^-10 : 9^-8 =
9^-2

Answer 2

b) 4^0+2^1-1^8
1+2-1 = 2

c) (20/3)^-3
(3/20)^3 = 27/8000

d) 8^5 × 8^-6
8^-1 = 1/8

e) 9^-10/9^-8
9^-10 × 9^8
9^-2 = 1/81

Qualquer coisa é só perguntar! Abraço.
