I will assume that everything after the radical sign is under the sign...
6√(64x^4y^2)
6√(8^2(x^2)^2(y^2)) removing all of the perfect squares...
6*8*x^2*y
48x^2y
Time taken for hare to catch up with the tortoise will be found as follows:
time taken=distance/(relative speed)
relative speed=(speed of hare-speed of tortoise)
speed of hare=500/20=25 cm/sec
speed of tortoise=250/50=5 cm/sec
relative speed will be:
(25-5)=20 cm/ sec
thus the total time taken for hare to catch up with the tortoise will be:
1000/20
=50 sec
Answer: 50 sec
I need a question or a problem to solve??
The value of c that makes up a perfect square trinomial is
9x^2 - 12x +c
