Mocniny a jejich výrazy
Zapiš výrazy jako mocninu, či mocniny, ve tvaru r^{n}, kde n ∈ ℤ pro a, b, x ≠ 0:
\large \Large \frac{{{a^{k+2}}}}{{{b^{k-1}}}}\large :\Large \frac{{a^{k}}}{{b^{2}}}\large
\large = {a^{2}} \cdot {b^{ - k}} \cdot {b^{4}} = {a^{2}} \cdot {b^{4-k}}
\large = {a^{2}} \cdot {b^{ - k}} \cdot {b^{3}} = {a^{2}} \cdot {b^{3-k}}
\large = {a^{2}} \cdot {b^{ - k}} \cdot {b^{2}} = {a^{2}} \cdot {b^{2-k}}
\large = {a^{3}} \cdot {b^{ - k}} \cdot {b^{3}} = {a^{3}} \cdot {b^{3-k}}
