Question

помогите решить пример ( 5/8-2/5)+3/20

Answer 1

(5/8-2/5)+3/20=9/40+3/20=3/8

Answer 2

$( \frac{5^{(5} }{8} - \frac{2^{(8} }{5} ) + \frac{3}{20} = ( \frac{25}{40} - \frac{16}{40} ) + \frac{3}{20} = \frac{9}{40} + \frac{3^{(2} }{20} = \frac{9}{40} + \frac{6}{40} = \frac{15^{(5} }{40} = \frac{3}{8}$
