Guys I'm sad because I haven't done my math in like 6 months because I hate radicals. :( Help me pwease? It's probably super easy but my lesson doesn't explain much and my teacher refuses to help. Change this radical to an algebraic expression with fractional exponents. 3√a

    a^(1/3). Basically the rule here is fairly simple. Say you have 2√x^3 (square root of x to the power of 3. What you do is take the "to the power of" portion and divide it by what kind of root it is (ie. squared is 2, cubed is 3...etc). So what you get is x^3/2

    @yololol No you are wrong \[\sqrt{b}=(b)^{1/2}\]

    Okay, it doesn't give it as an option to be an exponent so maybe they'll just assume it's an exponent and I'll hope for the best. Thank you! Sorry about my dumb questions. OMG it's Joker!! :D xD
