Question

3. Verify the property, x*(y*z) = (x + y)*z
for each of the following:
a. x=5/4,y=1/2 andz=-7/5​

Answer 1

given=>

x*(y*z) = (x + y)*z------(1

x=5/4,y=1/2 and z=-7/5-------(2

solution=>

EQ (2 value put on EQ(1 LHS

LHS

$= \frac{5}{4} ( \frac{1}{2} \times \frac{ - 7}{5} ) \\ \\ = \frac{5}{4} \times \frac{ - 7}{2 \times 5} \\ \\ = \frac{ - 7}{8} ..(3$

now

EQ (2 value put on EQ(1 RHS

RHS

$= ( \frac{5}{4} + \frac{1}{2} ) \frac{ - 7}{5} \\ \\ = \frac{7}{4} \times \frac{ - 7}{5} \\ \\ = \frac{ - 49}{20}$

RHS not equal lhs
