Question

If A-=15, B=16 and C=17, then which of the following is not true?
a (B)+C A+ (B+ C)
b. (Ax B) C Ax (Bx C)
c A (B C)=(A x B) +(B C)
D A×(B+C) = (A× B)+ (A×C)​

Answer 1

Answer:

A=15,B=16,c=17

(a)L.H.S:

(A+B)+C=(15+16)+17=31+17=48

R. H. S: A+(B+C)=15+(16+17)=48

(true)

(b) true

(c)A×(B×C)

=15×(16×17)

=15×272

=4080

(A×B)+(B×C)

=15×16+16×17

=240+272

=512(false)

(d) true
