## anonymous 5 years ago 7 sqrt 2 - 3 sqrt 2

1. anonymous

$7 \sqrt2 - 3\sqrt2 = 4\sqrt2$ ^_^

2. anonymous

7rt2 - 3rt2 = 4rt2

3. anonymous

because according to distributive law of multiplication under addition: ab + ac = a(b + c)

4. anonymous

so here is 7rt 2 - 3rt 2 we can see that rt 2 is common in both the terms: we will get: rt2(7-3)

5. anonymous

so rt2(7-3) = rt2 ( 4) = 4*rt2 = 4rt2
