to the people who answered the "if 1=5 nad 2=25......"  read this?

here we are talking about a  sequence , so we try to get the formula of the sequence than the result.\nBut the proposed solution that 1=5 it's completly  wrong

assuming your expression equals 0\nx^2-25-0\n(x+5)(x-5)=0\nx=5 or -5

Well the correct is both 15 and 95.\nTaking 15 :\n(1)^2 + (5)^2 = 26 which is 11 more to 15\n2(1)(5) = 10 which is  5 less than 15\n\nTaking 95 : \n(9)^2 + (5)^2 = 106 which is 11 more to 95\n2(9)(5) = 90 which is 5 less than 95

Think as follows.\n\n1 is 5^1 = 5\n\n2 is 5^2 = 25\n\n3 is 5^3 = 125\n\n4 is 5^4 = 625\n\nSee the pattern?, For the nth row is 5^n.\n\nHence, for what you wanted,\n\n5 is 5^5 = 3125\n\nAnd buddy, I always think before answering... :)\n\nRegards

3=2 did get a correct answer...maybe you need to review your rules of square roots.

There's a mathematical riddle that claims to "prove" 1 = 2, but if you examine it closely enough, it turns out to be dividing by 0.  Sorry I csn't remember the riddle.

I'm sure it isn't correct, though I'm not totally sure what you've done.  It looks to me as if you've raised both sides of \naⁿ + bⁿ= cⁿ\nto the power 1/n.  The trouble is, when you do this the left side is not equal to\n(aⁿ)^(1/n) + (bⁿ)^(1/n)\n\nYou can see this if you consider\n(5^3 + 2^3)^(1/3)= 133^(1/3), which is just slightly over 5, definitely not equal to\n(5^3)^(1/3) + (2^3)^(1/3)\n= 5 + 2\n= 7

Does what you have written means f(x) = 4*x - 5/(16*x^2) - 25 or f(x) = 4*x - (5/16)*x^2 - 25? Make it clear.

f = 30 x 25 x 20 x 15 x 10 x 5 x the other 24 integers. \n\nSo f contains 7 factors of 5 (25 supplies 2 of them) and more than 7 factors of 2. \n\n(The 15 even numbers supply a total of more than 15 such factors as there are three powers of 2 and 3 of the other even numbers (12, 20 & 28) are also divisble by 4 and 24 is divisible by 8)\n\nBut 7 factors of 2 is all we need for our purposes and even if we had a multitude of surplus 2s, they cannot give us another 10\n\ni.e. f contains 7 factors of 10. And ONLY 7 such factors as each 10 can only be made up of a 5 and a 2 \n\nso d = 7 is the only possible answer, given that we are told that d >6\n\nGENERALISING:\n\n50, 75, 100, also supply two 5s to a factorial they are part of, \n\nso for f = 55! and d> 12, d must = 13\nso for f = 80! and d> 18, d must = 19\nso for f = 105! and d> 24, d must = 25\n\nhowever\n\nfor f = 130! and d> 30, d is not 31 but 32\nCAN YOU SEE WHY?

It all dependent on ho your look at the question, o asking the question. it is stander to belie that 2 + 2 = 4. if you take it out of perspective you could see that that 2 puls 2 =22

.5 + .5 + .25 + 1.25 = 2.5\n\nTwo and a half.\n\nI like it, very funny!

Pretty slick, RED\n\nYou came on pretending that "someone else" had a problem and even gave out a wrong answer on purpose.  Clever!\n\nI can see through that, you just wanted people to give you the right answer without giving you the whole "Do your own homework" speech.\n\nNice! Score one for you.  Unless, of course, I am giving waaaay too much credit for such an ingenious plan.  In which case, x=2, not 24.

31 / 5\n\nThat's because .2 is 1 / 5, so I just converted the 6 to 30 / 5 and added one more.

2√5  \n\nif you have √20 its √4*5\n√4 is 2\nso you have 2√5

it's not factored completely if you leave it as a^2-25 so the proper answer is 5(a-5)(a+5)

It means (X + 5)/3 = 25 I guess.
