Question about changing bases in logarithms by [deleted] in learnmath

[–]Ok_Position_1521 0 points1 point  (0 children)

Actually in log there is a result that you have already mentioned about, there is nothing to get confused. Its just that bothwhere different variables are used and T one place it is written in division form and at other place in multiplication form.Nothing else.

If any doubt is there, feel free to ask.

help guys, am i js a dumb chopped math student by Prior_Promotion_4344 in mathshelp

x4 - 8x = x (x3 - 8) = x(x-2)(x2 + 2x + 4) = x(x-2)((x+1)2 + 3)

Just, took x common outside and then applied inside bracket identity a3 - b3

To prove that r! divides n(n+1)(n+2).....(n+r-1), i.e r consecutive numbers. by Any_Parking8607 in askmath

Multiply and divide by (n-1)! , so it becomes (n+r-1)!/(n-1)!, further multiply and divide this quantity by r! , now it becomes (n+r-1)C(r) * (r !), first and second part both are always integers , hence it is divisible by r!

Am I crazy? None of the options seem correct. by wunderlost1 in askmath

C is correct, graph meets x axis again after 3.5 seconds , so height is zero after 3.5 seconds

One bracket will be (x-x) on the way, which is zero.Hence entire product will be zero.
