Answer 2

If you found any mistake please give me a valid reason only

1) False

reason : Odd multiplied by odd is always odd.

for eg 3³=27

2) True

reason :A perfect cube will end with odd number of zeroes

for e.g. : 10³ = 1000

3) True

reason : 5 multiplied by 5 any number of times always gives 5 at unit’s place

for e.g. : 5³=125, 25³=15625

4)False

reason : 2³= 8 here the cube of 2 is 8

5) False

reason : the smallest three digit no. 10³=1000

6) False

reason : 99 is the largest 2 digit number; 993 = 989901 is a 6 digit number

7) True

reason : 2³ is 8 which is smallest one , also 1³=1
