If a and b are whole number such that a^(b)=512 where a gt b and 1 lt b lt 4 then bsqrt(a) =

Property 5 If ab and c are whole numbers such that a-b=c then b+c=a .

Property 1 If a and b are two numbers such that a > b or a = b then a - b is a whole number. If a < b then subtraction a - b is not possible in whole numbers.

AN IMPORTANT RESULT If a and b are two whole numbers such that q is the quotient and r is the remainder when a is divided by b then

COMMUTATIVITY If a and b are any two whole numbers then a+b=b+a

CLOSURE PROPERTY If a and b are two whole numbers then a+b is also a whole number.In other words the sum of any two whole numbers is a whole number or whole numbers are closed for addition.

CLOSURE PROPERTY If a and b are two whole numbers then their product a xx b is also a whole number.

Property 1 If a and b( b not equal to zero are whole numbers then a-:b( expressed as (a)/(b)) is not necessarily a whole number.

Assertion : If a is a whole number, then a+0=0+a=a . Reason : If a and b are whole numbers, then a+b is also a whole number.
