Express √2/√48-√8-√27 in the form p+q√r where p, q and r are rational numbers

(a) 22√48√−8√−27√

= 22√16×3√−4×2√−9×3√

= 22√43√−22√−33√

= 22√3√−22√

= (22√3√−22√)(3√+22√3√+22√)

= 26√+4(2)3+26√−26√−4(2)

= 26√+83−8

= 8+26√−5

= −85−26√5

= p=−85;q=−25;r=6

(b) V=Alog10(M+N)

log10(M+N)=VA

10VA=M+N

N=10VA−M
