X3 squared = - 125, what is the value of x ?

If x3 = 125, what is the value of x?

3

5

12

42

Step-by-step explanation:

Option B.

In this question the given expression is x³ = 125 and we have to find the value of x.

x³ = 125

x³ = 5³

x = ∛5³

x =

x =

x = 5

If x3 = 125, what is the value of x?

Step-by-step explanation:

Option B.

In this question the given expression is x³ = 125 and we have to find the value of x.

x³ = 125

x³ = 5³

x = ∛5³

x =

x =

x = 5

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
