If m and n are two natural numbers and mn=32, then nmn isa. 52 b. 53 c. 510 d. 512

The given condition is that m and n are two natural numbers and mn = 32. The natural numbers that satisfy this condition are m = 4 and n = 8 or m = 8 and n = 4.

Now, we need to find the value of nmn.

If m = 4 and n = 8, then nmn = 848 = 256.

If m = 8 and n = 4, then nmn = 484 = 128.

So, the value of nmn is neither 52, 53, 510, nor 512. There seems to be a mistake in the options provided.
