c)
log100 = 2, ponieważ 10² = 100
log√10 = 1/2, ponieważ 10^1/2 = √10
log0,01 = -2 , ponieważ 10⁻² = 0,01
log∛10 = 1/3, ponieważ 10^1/3 = ∛10
2.22
c)
log₅25√5 = log₅5²*5^1/2 = log₅5 = 1, ponieważ 5¹ = 5
log₂√2 = 1/2, ponieważ 2^1/2 = √2
log₆6√6 = log₆6*6^1/2 = log₆6^3/2 = 3/2, ponieważ 6^2/3 = √6³ = 6√6
log₃√3 = 1/2, ponieważ 3^1/2 = √3
log₇∛49 = log₇7^2/3 = 2/3, ponieważ 7^2/3 = ∛7² = 49
