How these question will get solve ? .

Ok so look

we have
2√3+3√3-4√3
easy
remember taht 2√3 means 2 times √3 or √3+√3
it tells how many of that
so just add the numbers
2+3-4=1
1√3 or √3 is answer

2.
first simplfy each radical

5√32=5(√16)(√2)=5(4)(√2)=20√2
2√50=2(√25)(√2)=2(5)(√2)=10√2
now we have
20√2+10√2
just add
30√2

1. √3
2. 30√2

Deja qué x = longitud6(x) = 48cm^2divide por 6: x = 8la área de longitud es 8 cm.
