Does 1 divide?
Yes, 1 can divide. Anything divided by 1 equals that number which was first divided. For example, x/1 = x. x divided by 1 equals x
How do you divide fractions by x?
Multiply by 1/x
Why is 6 to the power 0 equal to 1?
Anything to the power 0 is 1. Using the laws of powers to get to x to the power n-1 from x to the power n you divide by n; eg to get 4 squared (16) from 4 cubed (64) you divide 64 by 4. If you start with x to the power 1 and want x to the power zero, you divide by x. And x divided by x is 1.
What is the prime factorization of 728 with exponents?
728 Divide by two. 364,2 Divide by two. 182,2,2 Divide by two. 91,2,2,2 Divide by seven. 13,7,2,2,2 Stop.
What is the answer to cos square x divide by 1 minus sin x?
cos2 x /(1 - sin x)= (1 - sin2 x )/(1 - sin x)= (1 + sin x)(1 - sin x)/(1 - sin x)= 1 + sin x
What do you get if you divide c by x and then divide result by v?
(c/x) /v = (c/x) * (1/v) = c/(x*v), so c divided by (the product of x and v).
How should you simplify x0?
If that is x to the power 0, then it = 1, irrespective of the value of x. Consider for example x =4. x squared is 16. To get from x to the power 2 to x to the power 1, you divide by x, giving 4 to the power 1 = 4. Similarly, to get from x to the power 1 to x to the power 0, you divide by x, giving 4 to the power zero = 1.
Limit x approaches 0 sinx divide x equals 1 evaluate limit x approaches 0 cos2x-1 divide x?
== == Cos2x - 1 = [1 - 2sin2 x] - 1 = - 2sin2 x; so [Cos2x - 1] / x = -2 [sinx] [sinx / x] As x approaches 0, sinx / x app 1 while 2 sinx app 0; hence the limit is 0.
What is the inverse of x divided by x plus 4?
The inverse of x is written as 1/x. If we divide that by x, we get 1/x/x, which can also be written as 1/x * x/1 = x/x = 1. Then we add 4, 1 + 4 = 5.
How do you solve 3(x-1)15?
If the question is 3(x-1) = 15, you divide 15 by 3. That tells you what x-1 is. Then you add 1. That's x.
What is a half divide by three?
1/2 x 1/3 = 1/6
Is there Number that can be divided by all number?
No. And the proof is simple. Suppose there were such a number, X. Then X+1 is also a number and X+1 does not divide X.
