Sederhanakanlah

1) 2√2 + √50 - √18 =
2) √500 =
3) √243 =
4) √18 - 6√3 + √48 =
5) √80 + 5√5 - √20 =

Answer 1

1) = 4+7.0-4.2=......
2) = 22.3
3) = 15.5

Answer 2

2) √500=√100.5=10√5

1) 2√2+√50-√18
=2√2+√25.2-√9.2
=2√2+5√2-3√2
=4√2

5) √80+5√5-√20
=√16.5+5√5-√4.5
=4√5+5√5-3√5
=7√5

3) √243=√81.3=9√3

4) √18-6√3+√48
=√9.2-6√3+√16.3
=3√2-6√3+4√3
=3√2-2√3
