She drinks 1/4th of the bottle and then another 1/6th of the bottle. So he drinks 3/12+2/12 of a bottle which is 5/12
30 + 8 = 38 desks
38 x 4 = 152 legs
If you did not add those eight desks then you will have 120 legs.
So, the amount of legs will go up by 32 if you add 8 more desks.
First, solve the bracket:
(-3)^2 = (-3)(-3) = 9
Next, simplify
[9]^5 = 9 x 9 x 9 x 9 x 9 = 59049
59049 is your answer
hope this helps
