so adding all these numbers we get

2-7-16-25-34-43-52-61-70

Use radical notation to rewrite each expression and simplify<br> 9 3/2

scoundrel [369]

Answer:

$9^{\frac{3}{2}}=\sqrt{9^3}=27$

Step-by-step explanation:

The fractional exponent m/n is often translated to radical form as ...

$x^{\frac{m}{n}}=\sqrt[n]{x^m}$

In this case, I find it easier to evaluate as ...

$x^{\frac{m}{n}}=(\sqrt[n]{x})^m=\boxed{(\sqrt{9})^3=3^3=27}$
