1. 2√10 * 8√10 = 16(10) = 160
2. √6/7 *√3/10 = √18/70 = √(9x2)/70 = 3√2/70
3. √75+√48 = √(25x3) + √(16x3) = 5√3 + 4√3 = 9√3
4. 3√6-24+2√150
= 3√6-24+2√(25x6)
= 3√6-24+10√6
= 13√6 - 24

1. 2√10 * 8√10=16*√(10*10)=16*√100=16*10 = 160
2. √6/7 *√3/10 =(√18)/70 = (3√3)/70
3. √75+√48 = √(25*3)+√(16*3)=5√3+4√3 = 9√3
4. 3√6-24+2√150
=3√6 -24 +2√(25*6)
=3√6 -24 +10√6
= 13√6 +24

1. 160
2. √9/35 or 3√35/ 35
3. 5√3 +4√3= 9√3
4. 13√6 -24

You must simplify the radical by finding its factors. For example, √24 could simplify to √6√4, and the √4 would, in turn, simplify to 2, making it 2√6. Find the factors and combine like terms and you'll be fine.

consider common expressions to be a common variable (x)
EX-
1. 2(x) * 8(x) = 16*x^2 = 16 * 10 = 160

if you can't figure the rest out you should ask a paid instructor for more help before you end up in a class that is way over ur head... g/l

I just saw ans#1, they are correct!
