evaluate the expression: log_7(3^4) - log_6(6^3)

[hollerback1]

Evaluate the expression:

log₇3^4-log₆6^3

Oh yeah, how do u make the exponent squared, or above the number?

Exponents - just HTML tags (without the spaces)

< s u p > exponent < / s u p >

Subscripts are similar

< s u b > subscript < / s u b >

Use log properties

log(a^b) = b*log(a)
log_a(a) = 1

That's about all you'll need on this one.

Use log properties

log(ab = b*log(a)
loga(a) = 1

That's about all you'll need on this one.

hmm, can you show me the steps plz.

I hav a quiz tommorow
