Question

Calcule o valor de Y=? em cada equação:


a) Log⁴ Y = 3

b) Logy 36 = 2

c) Log⁹ Y = 1

d) Logy 125 = 3

e) Log² Y = 5​

Answer 1

a)
log₄ y = 3

y = 4³
y = 4.4.4
y = 64
----------------------------------
b)

log 36 = 2
y

36 = y²
6² = y²

6 = y
y = 6
-------------------------------------
c)
log y = 1
9

y = 9¹
y¹ = 9¹
y = 9
--------------------------------------
d) log 125 = 3
y

125 = y³
5³ = y³
5 = y
y = 5
--------------------------------------
e) log y = 5
2

y = 2⁵
y = 32
-----------------------------
