Which expression is equivalent to 100 n2 − 1? (10n)2 − (1)2 (10n2)2 − (1)2 (50n)2 − (1)2 (50n2)2 − (1)2

You know that .

Use the property to state that

Then the expression is equivalent to

correct choice is A.

The expression  100n² - 1 is equivalent to (10n)² - 1² .

Step-by-step explanation:

As given the expression in the question be as follow

= 100n² - 1

Take

= (10n)² - 1²

As

(10n)² = 100n²

1² = 1

Put in these values in the expression

=  (10n)² - 1²

= 100n² - 1

Therefore the expression  100n² - 1 is equivalent to (10n)² - 1² .

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
