Answer:
x^6
Step-by-step explanation:
Given (x^8)^3/4
To find : simplified as much as possible, x is raised to what exponent.
Solution : We have given that (x^8)^3/4
By the exponential rule : x^a(b) = x^ab
Then we have
=x^(8/4 *3)
=x^(2 *3)
=x^6
Answer:
9/44 of an hour, or just over 12 minutes
Step-by-step explanation:
Person 1 + Person 2 divided by Person 1 x Person 2 = Both together
9 + x / 9*x = 5
9+x/9x = 5
Multiply both sides by 9x
9 + x = 45x
Subtract x from both sides
9 = 44x
Divide by 44 to get x.
9/44 of an hour
Train A speed= 70 km/h north
Train B speed= 75 km/h south
Opposite directions= add speeds 70+75=145
Distance= 435 Km
Time= d/s; 435/145= 3 hours
It would take 3 hours for the trains to be 435 kilometers apart
