# Help in typing

i want to pose a problem to brilliant and i need to type seventh root of a number for it. but the math formatting guide gives me an option for only a square root. Does anybody know how to do it?

Sort by:

\sqrt[7]{a}

In math brackets this appears as $$\sqrt[7]{a}$$. Alternatively, you can also type a^{\frac{1}{7}}, which appears as $$a^{\frac{1}{7}}$$ within proper math brackets. · 3 years, 9 months ago
