Question

2)De valor ,na forma decimal,de: a)2-1 b)2-5 c)(-2)-2 d)-2-4 e) -(-4)-3 f)-(-10)-1 g)10-3 h)5-2

Answer 1

a)2-¹ = -1/2

b)2-⁵ = (1/2)⁵ = (1/2)(1/2)(1/2)(1/2)(1/2) = -1/32

c)(-2)-² = (-1/2)² = (-1/2)(-1/2) = 1/4

d)-2-⁴ = -1/2⁴ = -(1/2)(1/2)(1/2)(1/2) = -1/16

e) -(-4)-³ = -(-1/4)³ = -(-1/4)(-1/4)(-1/4) = -(-1/64) = 1/64

f)-(-10)-¹ = -(-1/10) = 1/10

g)10-³ = 1/10³ = 1/10.1/10.1/10 = 1/1000

h)5-² = 1/5² = 1/5.1/5 = 1/25
