It's log and stuff like that, pretty simple stuff but I have trouble studying alone. Can anyone help? I've got a practice exam that'll be really similar so it should be easy. I can get in voice chat to do it

i'm so confused on question 4

#

Logbase5(1/125)

#

1/x = x^-1
Logbase5(1/125) = Logbase5(125^-1)

#

Pull out thre -1 form the exponent

my teacher said it equals 3

#

i have no idea how

wise moth
#

3?

#

Just 3?

#

It’s not 3

#

Logbase5(125^-1) = -1•logbase5(125)
5^what = 125

unique shadow
#

that's 3

#

i figured out how to do it anyway

#

now 'im confused on question 7

#

it's rationalizing a fraction
