If 25^5 × 5^(-1) = (125)^x , then what is the value of x?  Choose the correct choice from the following
A) 2
B) 3
C) 4
D) 5
E) 6
25^5 × 5^(-1) = (125)^x   (5^2)^5 × 5^(-1) = 5^3x   5^10 x 5^(-1) = 5^3x; Since all of the bases are the same now, we can equate the exponents in the next step   10-1 = 3x   9=3x   x=3   Ans. 3)3
