thats hard to decipher into a problem... can you re write it better or explain it more?
amistre64
  • amistre64
is this it? \[\frac{(a^{-5b})^{-4}}{ab^3}\]

the slash after the 4 is actually indicative of the fraction. wasn't sure how to write that

exponents of exponents multiply together... a^(20b) ------- ab^3
amistre64

division of like bases subtrats exponents: a^b --- = a^(b-c) a^c

  • amistre64
a^(20b-1) --------- seems to be the best I can get from it... b^3

its hard to write equation on here lol

we could try log rules.... maybe :) 20b log(a) - log(a) + 3log(b)...not sure how that would help tho :)

I noticed. I tried to use the equation template but it got confusing
amistre64
  • amistre64
you can make a fraction by typing 'frac{top}{bottom}' into it directly

exponents are ^{number}

sooo close.....
amistre64
