Verify [3/4+-2/5]+-7/10=3/4+[-2/5+-7/10]
Answers
Answer:
Proved
Step-by-step explanation:
For the given question we need to proof that
................(i)
proof :
Solve LHS part
Therefore, we have
First solve this part , so find the LCM of 4 and 5 .
Step1:
⇒ (where 20 is the LCM of 4 and 5 )
⇒
Again take the LCM of 20 and 10 which is 20 ,
Now = .
So, LHS = .
Solve RHS:
Step2:
Similarly from step1
Here we have ,
= (where LCM of 5 and 10 is 10 )
⇒
Again find LCM of 4 and 10 which is 20 .
Therefore ,
= .
Final answer:
Hence , here we proved that LHS = RHS which is .
Given: Two expressions and
To verify: =
Solution:
Taking L.H.S.
⇒
L.C.M of 4 and 5 = 20
⇒
⇒
L.C.M of 10 and 20 = 20
⇒
Taking R.H.S.
⇒
L.C.M of 5 and 10 = 10
⇒
⇒
L.C.M of 4 and 10 = 20
⇒
∴ L.H.S = R.H.S =
Hence, verified that =
