Question

log2 z 1 przez pierwiastek 4 stopnia z 8

Answer 1

log₂(1/⁴√8) = x

2^x = (⁴√8)^⁻¹

2^x = (8^¼)^⁻¹

2^x = [(2³)^¼]^⁻¹

2^x = 2^⁻¾

2^x = -3/4   

x = -3/4

 

log₂(1/⁴√8) = -3/4

Answer 2

⁴√8¹ = 8^(1/4) = (2^3)^(1/4) = 2^(3/4)

1 / ⁴√8¹ = 2^(-3/4)

 

log2  1 / ⁴√8¹ = log2  2^(-3/4) = -3/4
