WebbNo. Sal originally had the equation sqrt (1.5/2). You can then multiply the part inside the parentheses by 1 represented as 2/2, giving us sqrt ( (1.5*2)/ (2*2)), which can be simplified to sqrt (3/4). We can then separate this into sqrt (3)/sqrt (4), where we can finally simplify it to sqrt (3)/2.
