Question

-16a^-3b^-5
------------- = ?
2a^-4b^2

Simplify the expression using properties of exponents.

Answer 1

similar to the others you have posted before.

Since the numbers are multiplied with each other you can split them apart like this

\[\large \frac{ -16a^{-3}}{2a^{-4} }*\frac{ b^{-5} }{ b^2 }\]

and solve them individually

Answer 2

the last part is the easiest so let's start there, \[\frac{ b^{-5} }{ b^2 }=?\]

Answer 3

-8a^7b^7 ?

Answer 4

close, but not correct

Answer 5

Your b looks right.

Answer 6

-8ab^7 ?

Answer 7

-3--4 =?
-5-2 = ?

Answer 8

it's either -8a
-----
b^7

Answer 9

or -8
----
ab^7

Answer 10

\[\frac{ -8a }{ b^7 } = -8a*b^{-7}\]

Answer 11

the latter option would be \(-8a^{-1} *b^{-7}\) which is different
