Given that the prime factorisation of 198 is 2x(3×3)x11. State the minimum integer value of
mylen [45]

Answer:

22

Step-by-step explanation:

198 = 2×3²×11

For 198n to be a perfect square, each prime factor must have an even exponent.  So the smallest 198n would be:

198n = 2²×3²×11²

198n = 4356

n = 22

Stells [14]

Step-by-step explanation:

- 5 - ( - 4) =  - 5 + 4 =  - 1 \\  - 4 - ( - 5) =  - 4 + 5 = 1 \\  - 4 - (5) =  - 4 - 5 =  - 9 \\ 4 - ( - 5) = 4 + 5 = 9

Therefore ranking them from least to most:

- 4 - (5) \\  - 5 - ( - 4) \\  - 4 - ( - 5) \\ 4 - ( - 5)

A plane flew 360km in 3 hrs when flying with the wind.With no change in the wind,the return trip took 4 hrs.Find the speed of th
morpeh [17]
Speed of the plane: 250 mph
Speed of the wind: 50 mph
Explanation:
Let p = the speed of the plane
and w = the speed of the wind
It takes the plane 3 hours to go 600 miles when against the headwind and 2 hours to go 600 miles with the headwind. So we set up a system of equations.
600
m
i
3
h
r
=
p
−
w
600
m
i
2
h
r
=
p
+
w
Solving for the left sides we get:
200mph = p - w
300mph = p + w
Now solve for one variable in either equation. I'll solve for x in the first equation:
200mph = p - w
Add w to both sides:
p = 200mph + w
Now we can substitute the x that we found in the first equation into the second equation so we can solve for w:
300mph = (200mph + w) + w
Combine like terms:
300mph = 200mph + 2w
Subtract 200mph on both sides:
100mph = 2w
Divide by 2:
50mph = w
So the speed of the wind is 50mph.
Now plug the value we just found back in to either equation to find the speed of the plane, I'll plug it into the first equation:
200mph = p - 50mph
Add 50mph on both sides:
250mph = p
So the speed of the plane in still air is 250mph.
