HELP with RADICAL problem

Test Preparation SAT Preparation
1

<p>Radical problems, even easy ones, tend to annoy me. I often have to switch to decimals to get the right answer. For example, could someone explain how to solve this problem, without changing to decimals that is:P</p>

<p>If x percent of y is 0.12 and y equals 4radicand3, what is the value of x?</p>

<p>The answer was radical 3, which I got, but by using decimals.</p>

<p>I'm not sure what I keep doing wrong.</p>

<p>X/100(y)=.12 ----I got that</p>

<p>this is where my problem is I think:</p>

<p>4radicand3x=12, how do you solve that!?!?</p>

<p>PS: I feel I was absent the entire week on radicals and exponents, hah.</p>

<p>i just did .12/4sqrt3, which gave me .017(and some decimals). Just multiply that by 100 to get a percent.</p>

<p>Thanks for the reply, but I’m looking for a way to solve this problem without decimals.</p>

<p>take it from me: the hard way leads to trouble</p>

<p>but
if you must go that way, you can do this:</p>

<p>4sqrt3 (x) =12
move the 4 to the other side,
x(sqrt3)=3
if it’s not obviously already, x is sqrt 3 (which is consistent with my 1.7blahblahblah answer)</p>
