a) -32/15 + 14/10 = -64/30 + 42/30 = -22/30
b) (7/21 + 6/21) : 10/9 + 2/7 = 13/21 * 9/10 + 2/7 = 117/210 + 2/7 = 117/210 + 60/210 = 177/210

a) √20 = √4 * √5 = 2√5
b) √180 = √4 * √45 = 2 * √9 * √5 = 2 * 3 * √5 = 6√5
c) √57 nie da się rozlożyc
d) 2√18 * √3 = 2 * √9 * √2 * √3 = 2 * 3 * √6 = 6√6
e) 2√2 * 2√8 * √3 = 2√2 * 2 * √4 * √2 * √3 = 2√2 * 2 * √2 * √3 = 8 * √3 = 8√3
