Penjelasan dengan langkah-langkah:
[tex]1). {243}^{3} = {3}^{72} \\ (81 \times 3) {}^{3} = {3}^{72} \\ ( {3}^{ {4}} \times 3) {}^{3} = {3}^{72} \\ (4 + 1)3 = 72 \\ 5 \times 3 = 72 \\ 15 = 72 \\ n = \frac{72}{15} \\ n = \frac{24}{5} [/tex]
[tex]2). {2}^{7} \div {2}^{3} = {8}^{72} \\ {2}^{7} \div {2}^{3} = ( {2}^{3} ) {}^{72} \\ {2}^{7} \div {2}^{3} = {2}^{216} \\ 7 - 3 = 216 \\ 4 = 216 \\ n = \frac{216}{4} \\ n = 54[/tex]
