Question

Help gan pake caranya yaa

Answer 1

F(x) = x^5 + 1

f-¹(x) = x^5 + 1
y = x^5 + 1
x^5 = y-1
x = ^5√y-1
f-¹(x) = ^5√(x-1)

f-¹(33) = ^5√(33-1) = ^5√32 = 2

f-¹(a) = 6
^5√(a-1) = 6
a-1 = 6^5
a = (6^5) - 1
a =

f(x) = 2^(3x+1)
f-¹(x) = 2^(3x) . 2
y = (2³)^x . 2
y = 8^x . 2
8^x = y/2
x = 8 log y/2
f-¹(x) = 8 log x/2

f-¹(8) = 8 log (8/2) = 8 log 4 = ⅔ . ²log2 = ⅔

nomor 3 kurang paham. maaf
