sqrt(75a^2) can be written as\n\nsqrt(15) * sqrt(5) * sqrt(a^2)\n\nSo cancel out the sqrt(5) in the numerator and denominator, take the square root of a^2, and you have\n\na * sqrt(15)\n\nThis cannot be simplified further.

well, (1/3)x^3 equals x\n\nso you can simplify it to (8/3)x + 2 = f(x)\n\nthat is a good start.

Just do the long division. So, for 20/21,\n21 goes into 200 9 times with a remainder of 11.\nThen 21 goes into 110 5 times with a remainder of 5.\nThen into 50 2 times with a remainder of 8.\nThen into 80 3 times with a remainder of 17.\nThen into 170 8 times with a remainder of 2.\nThen into 20 0 times witha remainder of 20,\nthen it repeats, so the decimal expansion is\n\n.952380952380952380.....

It's the same thing as cube root (3a^2 / 9a) which simplifies to:\ncube root (a / 3).\n\nYou don't want a radical in the denominator, so multiply top and bottom by 9.\ncube root (9a / 27)\n\nThis comes out to cube root (9a) / cube root (27) or:\ncube root (9a) / 3.

Re: ³√(5/2)\n\nIf you need an approximation it is (5/2)^(1/3) on your calculator (as stated above)\n\nIf you want it exactly then you can write it as ³√(5/2) (also as stated above)\n\nIf you want to express it exactl;y BUT with a rational denominator then:\n\n³√(5/2) = ³√5 / ³√2 * ³√(2²) / ³√(2²) \n= ³√20/³√(2³)\n= ½ ³√20

Find the square root of 7 squared minus 3 squared.\nI got 6.3 for your #16 question

$25 x .20 = $5\n\n$30 x .25 = $7.50\n\nThat is about the shortest way to them - just change the % to a decimal and multiply, remembering to put the decimal point in the right place.  I hope this helps.

= 16ab/20ab^2\n= 4/5b // 16 and 20 can be reduced by 4, and an a and a b cancels out\n\n3*3*3*3*3 = 3^5\n3*3 = 3^2\n3^5/3^2 = 3^3\n= 3*3*3

No.  It is sqrt{25 / 3} = sqrt{25} / sqrt{3} = 5 / sqrt{3} = 5 sqrt{3} / sqrt{9} = 5 sqrt{3} / 3.

You figure the square root of each number separately...you've probably learned that in class alredy (how to do that)...then you take reach result, and multiply them together for your final answer.\n\nUse your textbook for reference...good luck!

well 3hrs 20 minutes is converted just like you do 3hrs 30 minutes. 20 divided 60 = .33 so it would be 3.33 hrs
