If we evaluate this expression, we square everything in the an initial set of parentheses; this means we have actually 10²n² - 1², or 100n² - 1.
You are watching: Which expression is equivalent to 100 n2 − 1?
This is the expression we were trying come equal.
The expression 100n² - 1 is tantamount to (10n)² - 1² .
Step-by-step explanation:
As offered the expression in the question be as follow
= 100n² - 1
Take
= (10n)² - 1²
As
(10n)² = 100n²
1² = 1
Put in these worths in the expression
= (10n)² - 1²
= 100n² - 1
Therefore the expression 100n² - 1 is indistinguishable to (10n)² - 1² .
The simplified form is
Step-by-step explanation:
Given the expression
we need to simplify the over expression.
Expression:
As
∴
⇒
which is compelled simplified form.

Which expression is identical to 100 n2 − 1? (10n)2 − (1)2 (10n2)2 − (1)2 (50n)2 − (1)2 (50n2)2 − (1)2Regroup:100n^2-1=10^2n^2-1=(10n)^2-1^2So the exactly answer is : (10n)^2-1^2To effort to variable a polynomial of 4 or an ext terms v no typical factor, an initial rewrite that in groups. Each group may perhaps be individually factored, and also the result expression might possibly lend itself to more factorization if a greatest typical factor or special kind is created.
