c) x = 4√27+5√72-7√32-6√75
x = 12√3+30√2-28√2-30√3
x = -18√3+2√2
y = 3√128+6√108-8√18-10√27
y = 24√2+36√3-24√2-30√3
y = 6√3
M(a) = x+y/2 = (-18√3+2√2+6√3)/2 = (-12√3+2√2)/2 = -6√3+√2
d) x = 5√700-2√200+3√567+4√50
x = 50√7-20√2+27√7+20√2
x = 77√7
y = 2√162+11√28-9√8-3√63
y = 18√2+22√7-18√2-9√7
y = 13√7
M(a) = (77√7+13√7)/2 = (90√7)/2 = 45√7
