Best ResponseYou've already chosen the best response.0What is the simplified form of 15 times x to the sixth power over 20 times y to the fifth power times the fraction 6 times ysquared over 5 times x to the fourth power ? 9 xsquared over 10 ycubed 9 x cubed over 10 ysquared 10 x cubed over 9 ysquared 10 x squared over 9 ycubed

Best ResponseYou've already chosen the best response.1so the question is \[\frac{15x^6}{20y^5} \times \frac{6y^2}{5x^4}\] so if you simplify it you get \[\frac{90x^6y^2}{100x^4y^5}\] start by simplfying 90/100 = then with the powers, use the index law for division, subtract the powers for the same base \[\frac{x^a}{x^b} = x^{a  b}\] if you get a negative power it just indicates a fraction \[x^{a} = \frac{1}{x^a}\] hope it helps

Best ResponseYou've already chosen the best response.0if there are same bases at the denominator and numerator you have to use exponent rule \[\huge\rm \frac{ x^a }{ x^b } = x^{ab}\]

Best ResponseYou've already chosen the best response.0in other words x^6 can be written as \[\huge\rm \frac{ x \times x \times x \times x \times x \times x }{ x \times x \times x \times x }\] now cancel x's

Best ResponseYou've already chosen the best response.0when you multiply same bases u should their exponent so that's how we can factor x^6

Best ResponseYou've already chosen the best response.0nope first one is right you will get negative answer then you have to use another exponent rule \[\huge\rm x^{m}= \frac{ 1 }{ x^m }\]

Best ResponseYou've already chosen the best response.0Using a directrix of y = 2 and a focus of (1, 6), what quadratic function is created? f(x) = one eighth (x  1)2  2 f(x) = one eighth (x + 1)2  2 f(x) = one sixteenth (x + 1)2  2 f(x) = one sixteenth (x  1)2 + 2
