a,b,and c are real numbers which of the following must be true?
A. \(a*(b+c)=a*b+a*c\)
B. \(a*(b-c)=a*b-a*c\)
C. \(\frac{b+c}{a}=\frac{b}{a}+\frac{c}{a}\)
D. \(\frac{b-c}{a}=\frac{b}{a}-\frac{c}{a}\)
E. \(\frac{a}{b+c}=\frac{a}{b}+\frac{a}{c
}\)
F. \(\frac{a}{b-c}=\frac{a}{b}-\frac{a}{c}\)
G. \((b+c)^a=b^a+c^a\)
H. \((b-c)^a=b^a-c^a\)
A. \(a*(b+c)=a*b+a*c\)

This is mostly a theoretical question rather than a calculation one
Using the distributive law of algebra you immediately could recognize that A,B,C, and D are the only correct choices
