How do you calculate elapsed time?
Answers
First tell me what elapsed time is
You take the time the event eneded and subtract it from the time the event started. Say a concert starts at 9:30 and ends at 11:00, 11:00-9:30= 1:30 the total time elapsed is an hour and a half(1:30).
Is the product of two perfect squares always a perfect square
Answers
hmm.... 5 squared is 25. 25 x 25 is 625 which is 25 squared.
SO, look at it this way
5² + 5² = same bases, so you add the exponents together to get 5^4
5^4 can be rewritten as (5²)² which is equal to 25²
This is a perfect square.
Review the "laws of exponents" for more help. :-)
