Exponents and logarithms and radical numbers...sooo simplify the expression
\[\sqrt{12}\]
The answer is \[2\sqrt{3}\] and you plz write how and why
12 = 4 . 3 Right ?
4=2^2 and we can answer this in radical 2 but dont have any answer for 3 so have : \[\sqrt{12}=\sqrt{4*3}=\sqrt{2^2*3}=\sqrt{3}*2\] Got it ?:)
@ojeano
Factorization and reduction: \[\sqrt{12} => \sqrt{4*3}=>\sqrt{4}*\sqrt{3} => 2\sqrt{3}\] Alternate using exponentials: \[\sqrt{12 } => (12)^{1/2} => (4*3)^{1/2} => (4)^{1/2} * (3)^{1/2} => (2^{2})^{1/2}*(3)^{1/2} => 2(3)^{1/2} =>2\sqrt{3)}\]
@kjburketx : Thank u !
Realy right and clear :)
@ojeano :Got it ????:)
I should have included these identities: 1) \[\sqrt{x} = x ^{1/2}\] , in general, \[\sqrt[a]{x} = x^{1/a}\] and 2) \[(x ^{a})^{b} = x ^{a*b}, so, (x ^{1/2})^{2} = x ^{1/2 * 2} = x ^{1} = x \] (Sorry... noobie getting used to the equation writer) :-)
omg yes thank you very much both of you @kjburktex and @E.ali
