8.92 is greater than 8.9
8.92 > 8.9
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
