2. b=-15 4. b=9 5. m=6 b=1 6. m=-4 b=140
Note that 80 is 16*5 and 96 is 16*6. Therefore, their sum is 16*5+16*6=16*(5+6), or 16*11. The sum is 176.
<span>(243)^(2/5) = ?

The 5 in the denominator means "take the 5th root".
The 2 in the numerator means "square".

</span><span>Taking the 5th root first you get:
(243)^(2/5) = 3^2
Now squaring gives you
3^2 = 9
So the answer is 9.
