Since x3 is a factor of x5, it is automatically the GCF.
The GCF is x5
x5-1 = (x - 1)(x4 + x3 + x2 + 1)
GCF of variables with exponents The GCF is the common variable with smallest exponent. example 9x4 - 27x6 the gcf is 9X4 because: 9x4 (1-3x2) = 9x4 - 27x6 In the same way: X5 is the GCF of X10 + x5 -x6 Because X5 ( X5 + 1 -x1) = X10 + x5 -x6 Remember the exponent rule if you are multiplyin the same base, you keep the base and add the exponents Hope this helps Btw this does not help me! anna
Here is one factor tree of 300: 300 20 x 15 (4x5) x (3x5) ((2x2)x5) x (3x5) You have reduced it to prime numbers, so you are finished. The factors of 300 are 2, 2, 3, 5, and 5.
Since x3 is a factor of x5, it is automatically the GCF.
This factors as (x5 - 4) (x5 + 4).
x2(x3 + 1) is the best you can do there.
The GCF is x5
14 ( x13, x5, x7)
Choose the lowest of the exponents. The GCF of x3 and x5 is x3
The GCF is x5
75 = 3 x 5 x 5
x5-1 = (x - 1)(x4 + x3 + x2 + 1)
(x^5 - y)(x^5 + y)
x10 =========================== Another contributor says: If the question means [ x5 + x5 ] then the sum is [ 2 x5 ].
x5 is an expression: there can be no answer to it.
