Put >,<or = in the boxes.
If n5=5 then 25n
Step 1: Finding the solution of n
Given, n5=5
⇒n5=5⇒n5×5=5×5[Multiplyingbothsidesby5]∴n=25
Step 2: Comparing the given equation 25n
L.H.S=25(1)
R.H.S =n
=25(2)
From (1)and(2)
L.H.S = R.H.S
∴25=n
Hence, If n5=5 then 25=n.
Question 2(c) :
Compare the fractions and put an appropriate sign:
45□55
If 25m=50 then 6m12
Put <, > or = sign in the boxes.
If 20x=100-5x then 4×20x4(100-5x)
Put the correct number in the box, so that the equation remains true.
If 4x-10=30 then 4x-10+5=30
