Someone help please ?

16

Step-by-step explanation:

(-3r ^-4) ^-4

(-3) ^-4  * (r^-4) ^-4

We know a^-b = 1/a^b   and c^d^f = c^(d*f)

1/(-3)^4 * (r)^((-4*-4)

1/81 * r^16

The value of m is 16

robert puts 2 in each row

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.
