Question

17¹⁵/51¹⁴×9⁷-5⁰=???
72¹¹/9¹⁰×2³⁴+53⁰

Answer 1

$\frac{ {17}^{15} }{ {51}^{14} } \times {9}^{7} - {5}^{0} = \frac{ {17}^{15} \times {3}^{14} }{ {(17 \times 3)}^{14} } - 1 = 17 - 1 = 16$

$\frac{ {72}^{11} }{ {9}^{10}\times {2}^{34}} + {53}^{0} = \frac{ {(8 \times 9)}^{11} }{ {9}^{10} \times {2}^{34} } + 1 = \frac{ {2}^{33} \times {9}^{11} }{ {9}^{10} \times {2}^{34} } + 1 = 2 \times 9 + 1 = 18 + 1 = 19$
