The "x" or "y" or abcdefg or any letter after a number is called a variable, and can be used to represent any number.
Assume that the consecutive numbers are: x, x+1, x+2, x+3 Then: x + x+1 + x+2 + x+3 = 1000 4x + 6 = 1000 4x = 1000 - 6 = 994 x = 248.5 The numbers are: 248.5, 249.5, 250.5, 251.5
1386 is the product of 2 x 3 x 3 x 7 x 11, all of which are prime numbers.
By the uniqueness of numbers, the answer is 49.
The first four prime numbers are 2, 3, 5, 7. The product of these numbers is 2 x 3 x 5 x 7 = 210
28 is the product of the prime numbers 2 x 2 x 7.
This depends on what "x" is. The sum of the first x odd numbers is equal to x^2 or x*x.
Call the numbers: x, (x+1), and (x+2)The sum is: x + (x+1) + (x+2) = 3x + 3 = 2073x = 204x = 68The numbers are 68, 69, and 70.
no x² is the product of 2 rational numbers in this case the same 2 numbers x and x The product of two rational numbers is always rational.
These are numbers x such that x = 1/x. But this means that x2 = 1. Try solving this last equation for x. (i.e. the only numbers are +1 and -1)
There are an infinite number of ways to multiply numbers and get a result of 728.If you look at products of only two numbers, and only positive numbers, and only whole numbers,then here are a few examples:1 x 7282 x 3644 x 1827 x 1048 x 9113 x 5614 x 5226 x 28And there are millions and billions more.
If you have a set of 45 numbers, then there is one combination that includes all 45 numbers and 45! = 45 x 44 x 43 x ... x 2 x 1 ≈ 1.19622 x 1056 permutations (ways of ordering) all 45 numbers.
[(aXbXc)X(dXeXf)]X[(aXbXc)X(dXeXf)]X[(aXbXc)X(dXeXf)]
168 = 2 x 2 x 2 x 3 x 7.
( 36! )/( 32! ) ( 4! ) = (36 x 35 x 34 x 33)/(4 x 3 x 2) = 58,905
The factor numbers are: 4 x 5 2 x 10 1 x 20
No.
Consecutive numbers: x is the first number (x)+(x+1)+(x+2)+(x+3) 4x+6=162 Therefore x=39 Numbers are 39, 40, 41 and 42
