find the least common multiple of 25 and 30, which is 150
so they will flash at the same time every 150 seconds which equals 2.5 minutes
48 is the lowest denominator
Hope this helps!
D. 4.81 x 10^13
Move the decimal to the right 13 times, because when you multiply by 10, you make the number bigger, when you divide you move the decimal to the left to make the number smaller.
48,100,000,000,000
The answer is 3.
If n^11/n^8=27 then, n^3=27.
The cube root of 27 is 3.
So the answer is 3.
