Hi Cynthia. For your first question, did you mean to ask if ( (x^{6 })(x^{4 }) )^{½ } = x^{5 } ? If so, then the answer is yes, because when you first combine (x^{6 })(x^{4 }) you use the exponent rule of multiplication: add the exponents, so this is (x^{10}). Then when you take this to the exponent of ½, you use the exponent rule of exponents: multiply the exponents. Since 10½ = 5 , then (x^{10})^{½} = x^{5}. Stephen La Rocque.>
