A Nice Square Root Math Simplification | How to solve!! 

(5√5+5)/(5√5-5) =√5+1/√5-1 =(6+2√5)/4 =(3+√5)/2

125=5^3, 25=5^2 thus (sqrt(125)+sqrt(25))/(sqrt(125)-sqrt(25))= (5*(sqrt(5)+1))/(5*(sqrt(5)-1))= (sqrt(5)+1)/(sqrt(5)-1)= (sqrt(5)-1+2)/(sqrt(5)-1)= 1+2/(sqrt(5)-1)= 1+2*(sqrt(5)+1)/4= 1+(sqrt(5)+1)/2= (3+sqrt(5))/2

9:18 Just fyi, you accidentally say “25 x 5 it is 50” when looking at 2•5•5 on the board. You do write the correct answer though. Your math explanations are a joy to watch.

“Satisfying” to watch 🙏

15 + 5 ÷15 - 5 =20 ÷ 10 =2

Класс!

2nd method is more simple.

The second method is better!

√125 = 5√5 ; √25 = 5. (5√5 + 5)/ (5√5 - 5) 5(√5 +1)/5(√5 -1) (√5+1)/(√5 +1)(√5+1)/√5+1) (√5+1)(√5+1)/((√5)²-1) (√5)²+2√5+1/(5-1) 5+1+2√5/4 6+2√5/4 (3+√5)/2 5-1/4 4/4 = 1
