5 2/5 - 1 3/5 equals?

3 and 4/5

Step-by-step explanation:

5 2/5 = 27/5

1 3/5 = 8/5

27/5 - 8/5 = 19/5 = 3 and 4/5

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
