$\frac{903^{\frac{1}{15}}}{1000^{\frac{1}{15}}} - 1 \cdot \frac{1000^{\frac{1}{15}}}{1000^{\frac{1}{15}}}$

Step 3

Combine $- 1$ and $\frac{1000^{\frac{1}{15}}}{1000^{\frac{1}{15}}}$ .

$\frac{903^{\frac{1}{15}}}{1000^{\frac{1}{15}}} + \frac{- 1000^{\frac{1}{15}}}{1000^{\frac{1}{15}}}$

Step 4

Combine the numerators over the common denominator.

$\frac{903^{\frac{1}{15}} - 1000^{\frac{1}{15}}}{1000^{\frac{1}{15}}}$

Step 5

The result can be shown in multiple forms.
