27X^3-8 = 0 27X^3 = 8 X^3 = 8/27 X = cubic root of 8/cubic root of 27 = 2/3

sqrt(27x)9 = (27x)9/2 = 27x4.5 While that can be simplified somewhat, it will leave a surd - sqrt(3x) - in the answer. Whether or not simplification is worthwhile, therefore, depends on what is to be done with the answer. > sq. root ( 279) ? on calculator: 27, x^y, 9, =, inv, x^2 > 2761448.4397

(2 - 3x)(9x^2 + 6x + 4)

27x + 23 or 27x - 23

Your question is ambiguous. (3x)^3 times (3x)^3 = 27x^3 times 27x^3 = 729x^6 or, if you meant 3x^3 times 3x^3 = 9x^6

(2 - 3x)(9x^2 + 6x + 4)

9x(x2+3x-10)

the answer is (3x-2)(9x squared+6x+4)

(8x + 9)(3x^2 - 1)
