(26)3= (\frac{2}{6})^3= (62)3=
We use the formula:
(ab)n=anbn (\frac{a}{b})^n=\frac{a^n}{b^n} (ba)n=bnan
(26)3=(22×3)3 (\frac{2}{6})^3=(\frac{2}{2\times3})^3 (62)3=(2×32)3
We simplify:
(13)3=1333 (\frac{1}{3})^3=\frac{1^3}{3^3} (31)3=3313
1×1×13×3×3=127 \frac{1\times1\times1}{3\times3\times3}=\frac{1}{27} 3×3×31×1×1=271
127 \frac{1}{27} 271
