Question

5 If a = 1/2, b = 3/4, verify the following:
(i) a × b = b *a​

Answer 1

Answer:

here

a = 1/2

b=3/4

to verify

a x b = b x a

we have to put he values

1/2 x 3/4 = 3/4 x 1/2

3/8 = 3/8

thus verified that the statement

a x b = b x a is verified

Answer 2

Given :

• If a = $\frac{1}{2}$ and b = $\frac{3}{4}$
• Verify : a × b = b × a

Solution :

$\large (i) \: \boxed{ \rm a \times b = b \times a} \\ \\ \twoheadrightarrow \: \: \frac{1}{2} \times \frac{3}{4} \: \: = \: \: \frac{3}{4} \times \frac{1}{2} \\ \\ \\ \large \sf \underline{ L.H.S : } \\ \\ \rm \frac{1}{2} \times \frac{3}{4} = \pink{ \frac{3}{8} } \\ \\ \\ \large \sf \underline{ R.H.S: } \\ \\ \frac{3}{4} \times \frac{1}{2} = \pink{ \frac{3}{8} } \\ \\ \\ \underline{ \boxed{ \purple{ \sf \: L.H.S \: = \: R.H.S }}}$

Therefore, $\underline{ \boxed{ \purple{ \sf a \times b = b \times a }}}$

$\large\underline{ \boxed{ \green{ \bf Hence, Verfied .\: }}}$
