370509
You can multiply it out like this:\n\n(2 + 3 times square root of x) times (4 - 5 times square root of x)\n\nequals (2 times (4 - 5 times square root of x)) + ((3 times square root of x) times ((4 - 5 times square root of x))\n\nequals (2 times 4) - (10 times square root of x) + (12 times square root of x) - ((3 times square root of x) times (5 times square root of x))\n\nequals 8 + (2 times square root of x) - (15 times x)

1.  add 1 toboth sides, then multiply by 3\n\n(x+4)^2=18  now take the square root of both sides\n\nx+4= +/- 3sqrt2\nx=-4 +/- 3sqrt 2\n\nyou also could use the quadratic formula\n\n\n2.  multiply num and denom by 3 - 2 sqrt3\n\n12-8sqrt3 +2sqrt3 -2sqrt6  all over -3\n\n\n3.  mult num and denom by 2 - sqrt 12 and get \n\n12-6sqrt12 all over -8\n\n12-12sqrt2  all over -8\n\n3-3sqrt2 all over -2

3√x times 3√x, this means you multiply 3√x to 3√x\n3√x * 3√x = (3*3)*(√x * √x)\n                = (9)*((x^(1/2)) * (x^(1/2)))\n                = (9)*((x^[(1/2)+(1/2)])\n                = (9)*((x^[1])\n                = (9)*x\n                = 9x\nWhich is not 9√x.\n\nI hope this makes clear.

1.) 3 &#92;/ x+2 - 4 = 3\nif you mean\n3 sqrt( x+2) -4 =3,\nthen\n3 sqrt(x+2) =7\nsqrt(x+2) = 7/3\nx+2 = 49/9\nx=49/9 -2\n\n2.) &#92;/ x+3 - &#92;/2x-8 = 1\nsqrt(x+3) -sqrt(2x-8) =1\nsqrt(x+3) = sqrt(2x-8) +1\nx+3 = 2x-8 +2 sqrt(2x-8) +1\n-x + 10 = 2 sqrt(2x-8)\nx^2 -20x + 100 = 4 ( 2x-8)\nx^2 - 28x  +132 =0\n'

Ex. (6,2) \n\n6 times 5 over 2 times 1\n6 x 5/2 x 1= 30/10 = 3/1\n\nEx. (7,4)\n\n7 times 6 times 5 times 4 over 4 times 3 times 2 times 1\n7 x 6 x 5 x 4/4 x 3 x 2 x 1= 840/12=70\n\nGet it?

Plug in each of the four answers.  The only one that works is (2), because you get\n\n | 3 (-2/3) - 3 | = 5\n | -2 - 3 | = 5\n | -5 | = 5\n 5 = 5
