<h2>Greetings!</h2><h3>When multiplying two roots together, you can rearrange the equation so that the roots are next to each other and so are the whole numbers:</h3>
2 x 3 x
x 
<h3>This means that 2 x 3 is simple, = 6,</h3><h3>But when multiplying

you simply multply the two numbers and put them in a square root:</h3>
=
<h3>But this can be square rooted to 6, which then means that the equation is now:</h3>
2 x 3 x 6 = 36
<h3>So the simplified form is 36.</h3>

(a) there are 8C2 = 28 ways of picking 2 girls from 8
And there are 21C4 = 5985 ways of picking 4 boys
Required number of ways for 2g / 4b = 28 * 5985 = 167,580
(b) at least 2 girls means combinations of 2g/4b , 3g,3b , 4g/2b , 5g 1b or
6 girls.
2g/4b = 167,580 ways
3g/3b = 8C3 * 21C3 = 56 * 1330 = 74,480
4g/2b = 8C4* 21C2 = 70 * 210 = 14,700
5g 1b = 8C5* 21 = 56*21 = 1176
6 girls = 8C6 = 28
adding these up we get the answer to (b) which is 257,964
10 is a common factor of 50 30 and 100. So is 2
