1 answer:
<u><em>Answer:</em></u>
Fraction of the whole band playing snare drum = of the whole band
<u><em>Explanation:</em></u>
<u>We are given that:</u>
Fraction of percussionists = of the whole band
Fraction of those playing snare drums = the percussionists
Now, to get the fraction of the whole band playing snare drums, we will need to multiply the fraction of percussionists by the fraction of percussionists playing snare drums
<u>This is done as follows:</u>
Fraction of the whole band playing snare drum = of the whole band
Hope this helps :)

Find the powers
$a^{2}=5+2 \sqrt{6}$
$a^{3}=11 \sqrt{2}+9 \sqrt{3}$
The cubic term gives us a clue, we can use a linear combination to eliminate the root 3 term $a^{3}-9 a=2 \sqrt{2}$ Square $\left(a^{3}-9 a\right)^{2}=8$ which gives one solution. Expand we have $a^{6}-18 a^{4}-81 a^{2}=8$ Hence the polynomial $x^{6}-18 x^{4}-81 x^{2}-8$ will have a as a solution.
Note this is not the simplest solution as $x^{6}-18 x^{4}-81 x^{2}-8=\left(x^{2}-8\right)\left(x^{4}-10 x^{2}+1\right)$
so fits with the other answers.
