x - 5 is in its simplest form.
Since x3 is a factor of x5, it is automatically the GCF.
This factors as (x5 - 4) (x5 + 4).
x times x times x times x times x
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
(x^5 - y)(x^5 + y)
x5-1 = (x - 1)(x4 + x3 + x2 + 1)
75 = 3 x 5 x 5
x10 =========================== Another contributor says: If the question means [ x5 + x5 ] then the sum is [ 2 x5 ].
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
