# How do you write with fractional exponents 3sqrta?

$\sqrt{a}$ this represents the square root of $a$.

Square root , can also be called as second root of $a$, so in terms of fraction, second root is a half power (color(red)(1/2)

( note: similarly cube root/third root is one third power , $\frac{1}{3}$)

so , sqrt a = a^(color(red)(1/2)

So,
3sqrt a = 3a^(color(red)(1/2)
