Question

Ce fac atunci cand am baza diferita si exponentii la fel??

Answer 1

$( \frac{ - 3}{5} ) {}^{20} \div ( \frac{ - 6}{10} ) {}^{20} = ( \frac{ -3 }{5} \div \frac{ - 6}{10} ) {}^{20} = ( \frac{3}{5} \div \frac{6}{10} ) {}^{20} =(3 \times \frac{2}{6} ) {}^{20} = ( \frac{2}{2} ) {}^{20} = 1 {}^{20} = 1$
