a)√2x=√8/:√2⇒x=√4
b)√3x=4√3/:√3⇒x=4
c)√5x-4√5=0/+4√5⇒√5x=4√5/:√5⇒x=4
d)√6x+√24=0/-√24⇒√6x=-√24/:√6⇒x=-√4=-2
e)√12x-4√3=0/+4√3⇒√12x=4√3⇒2√3x=4√3/:2√3⇒x=6
f)√27+2x=√75⇒3√3+2x=5√3/-3√3⇒2x=2√3/:2⇒x=√3
a) √2x = √8 => x = √8/√2 = 2√2/√2 = 2
b) √3x = 4√3 => x = 4√3/√3 = 4
c) √5x - 4√5 = 0
√5x = 4√5 => x = 4√5/√5 = 4
d) √6x + √24 = 0
√6x = -√24 => x = -√24/√6 = -2√6/√6 = -2
e) √12x - 4√3 = 0
√12x = 4√3 => x = 4√3/2√3 = 2
f) √27 + 2x = √75
2x = √75 - √27
2x = 5√3 - 3√3
2x = 2√3
x = √3
