How To Solve: Exponents
Attached pdf of this Article as SPOILER at the top! Happy learning! Hi All,
I have recently uploaded a video on YouTube to discuss

Simplifying = - 1 (for all odd values on n)
= + 1 (for all even values of n)
Simplifying = 1 if n is 0
= +ve if n is even (except n = 0)
= -ve if n is odd
= 0 if k=0 and n≠0
= not defined if k=0 and n=0
Simplifying = 0 , for all n ≠ 0
Simplifying = 1 ( Always)
Simplifying =
Simplifying If the base of two exponents is same and if we are multiplying the exponents, then we can keep the same base and add the powers.Simplifying If the base of two exponents is same and if we are dividing the exponents, then we can keep the same base and subtract the powers.Simplifying If the power of two exponents is same and if we are multiplying the exponents, then we can multiply the bases and keep the same powerSimplifying Simplifying Simplifying Adding exponents with same base and powerIf we are adding two or more exponents with the same power, then we can add them like normal variables is ALWAYS divisible by x-yEx: If we take n = 2 then we have,
=
= ( x - y ) * ( x + y) = divisible by x - y
is divisible by x+y when n is EVENEx: If we take n = 1 then we have,
=
= ( x - y ) => NOT divisible by x + y
Ex: If we take n = 2 then we have,
=
= ( x - y ) * ( x + y) => divisible by x + y
is divisible by x+y when n is ODDEx: If we take n = 2 then we have,
=
=> there is NO way in which we can express this as (x+y) * some other integer => NOT divisible by x + y
Ex: If we take n = 3 then we have,
=
= ( x + y ) * (
) => divisible by x + y
is NEVER divisible by x-yEx: If we take n = 2 then we have,
=
=> there is NO way in which we can express this as (x-y) * some other integer => NOT divisible by x - y
Ex: If we take n = 3 then we have,
=
= ( x + y ) * (
) => there is NO way in which we can express this as (x-y) * some other integer => NOT divisible by x - y
Hope it helps!
Good Luck!
