324 or 32×4


Open in App
Solution

I] 324 is of the form amn

Here, a=3,m=2,n=4

So, amn=am×n

then 324=32×4

=38.

Now, 38=3×3×3×3×3×3×3×3 (3 is multiplied 8 times)

=6561.

Hence, 324=6561 ……………………(1)

II] 32×4 = 3×3×4 (As, 32 means we have to multiply the integer 3 two times)

=36.

Hence, 32×4=36 ……………………(2)

From (1)and(2),

6561>36

Therefore, 324>32×4
