Very useful thank you!
√(x+35)=√x+√5(√(x+35))²=(√x+√5)²x+35 = x+5+ 2√(5x)35 = 5+2√(5x)35-5 = 2√(5x)30 = 2√(5x)30/2 = √(5x)15 = √(5x)(15)² = √(5x)²225 = 5x45 = x Ans
How do you get the music?
Nice solution! Thank you!
Hello, Math Hunter! Happy New Year ;)
Happy new year!

@2:40 - Just square both sides there:( (2√(5) * √(x) ) ^ 2 = (30 )^24 * 5 * x = 90020x = 900x = 900 / 20x = 45No need to do the rationalization stuff.
Excellent ! Thanks so much !
Excelente.

Very useful thank you!
√(x+35)=√x+√5
(√(x+35))²=(√x+√5)²
x+35 = x+5+ 2√(5x)
35 = 5+2√(5x)
35-5 = 2√(5x)
30 = 2√(5x)
30/2 = √(5x)
15 = √(5x)
(15)² = √(5x)²
225 = 5x
45 = x Ans

@2:40 - Just square both sides there:
( (2√(5) * √(x) ) ^ 2 = (30 )^2
4 * 5 * x = 900
20x = 900
x = 900 / 20
x = 45
No need to do the rationalization stuff.
