sqrt(162) = 9*sqrt(2)

A Huge ASS
First, note that radical 4 is 2. So 3xradical 4 is just 6, Now we have 6+2 radical 3. You can't do much with this except factor out a 2 if you want 2(3+Radical 3)
5/9 OR 0.5 repeating.. here's how: "radical 5 over 3" times "radical 5 over 3" (because squaring means to multiply a number by itself) is "radical 25 over 9". this is not complete: the square root of "25" is "5" so the final answer is 5/9. "5" divided by "9" is "0.5 repeating".
9*radical(3)/2 = 4.5*radical(3) = 7.794 approx.
√2 x √2 = (√2)2 = 2

Ahh ok radical 40 is equal to 2 radical 10
2 radical 30
40
first the two numbers have the same radicand which is radical 2 so we just add the numbers before them to become 7 radical 2
1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.
sqrt(162) = 9*sqrt(2)
radical(14)*radical(2) = 2*radical(7) Without further information available we will consider only the square roots. The square roots of 14 are +3.741 and -3.741, similarly the square roots of 2 are+1.414 and -1.414 and so we can have four products 1) (+3.741) X (+1.414) = +5.155 2) (-3.741) x (+1.414) = -5.155 3) (+3.741) x (-1.414) = -5.155 4) (-3.741) x (-1.414) = +5.155 Expressions 1 and 4 are equal, expressions 2 and 3 are equal. Hence the product of radical 14 times radical 2 can be +5.155 or -5.155
factor the 18. 18=2x3x3. Take out the 3 because it is squared. 5x3 radical 2=15radical2
2/3 = sqrt( 4/9 )
