Division av kvadratrötter

När man dividerar kvadratrötter, t.ex.

\frac{2}{3}

kan detta skrivas som

\frac{2}{3}

. Vi kan visa varför genom att skriva om täljaren och nämnaren

som potenser och därefter använda potenslagarna.

\frac{2}{3}

$a = a^{1 / 2}$

\frac{2 ^{1 / 2}}{3 ^{1 / 2}}

$\frac{a ^{c}}{b ^{c}} = (\frac{a}{b})^{c}$

(\frac{2}{3})^{1 / 2}

$a^{1 / 2} = a$

\frac{2}{3}
