Question

1.51. Есептендер: 1) 17¹3 3) 17²-17³ 5¹6-5 5¹8 2) 4 - 48; 0,3¹2 0,3-0,35-​

Answer 1

$1) \: \: \: \: \: \frac{ {17}^{9} \times {17}^{5} }{ {17}^{13} } = \frac{ {17}^{14} }{ {17}^{13} } = 17$

$2) \: \: \: \: \: \frac{ {4}^{15} }{ {4}^{5} \times {4}^{8} } = \frac{4 {}^{15} }{ {4}^{13} } = {4}^{2} = 16$

$3) \: \: \: \: \: \frac{ {5}^{16} \times {5}^{4} }{ {5}^{18} } = \frac{ {5}^{20} }{ {5}^{18} } = {5}^{2} = 25$

$4) \: \: \: \: \: \frac{0.3 {}^{12} }{ {0.3}^{4} \times {0.3}^{5} } = \frac{ {0.3}^{12} }{ {0.3}^{9} } = {0.3}^{3} = 0.027$
