Which is equivalent to 5 Square root of 1215^x

tia_tia [17]

Answer:

$(3\sqrt[5]{5} )^{x}$

Step-by-step explanation:

Given that

$\sqrt[5]{1215^{x} }$

=> $1215^{\frac{x}{5} }$ Using radical rule

=> $(3*3*3*3*3*5)^{\frac{x}{5} }$

=> $(3^{5} * 5 )^{\frac{x}{5} }$

=> $(3^{5*\frac{1}{5} } * 5 )^{x}$

=> $(3*5^{\frac{1}{5} } )^{x}$

=> $(3\sqrt[5]{5} )^{x}$

You travel between these two mile markers and then find your average speed in miles per hour. Which equation does NOT represent

Jet001 [13]

Answer:

The correct option is C.

Step-by-step explanation:

The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.

So total time taken by car is

$4:30-3:00=1:30$

It means total time taken by car is 1.5 hour.

The distance in first figure is 50 miles and the speed in second figure is 155 miles.

So total distance travelled by car is

$155-50=105$

It means total distance travelled by car is 105 miles.

The formula of speed is

$Speed=\frac{Distance}{Time}$

$Speed=\frac{105\text { miles }}{1.5\text{ hours}}$

Therefore option B represents the solution. Option B is incorrect.

Multiply both sides by 1.5 hours.

$1.5\text{ hours}\times Speed=105\text { miles }$

Therefore option D represents the solution. Option D is incorrect.

Divide both sides by speed.

$1.5\text{ hours}=\frac{105\text { miles }}{Speed}$

Therefore option A represents the solution. Option A is incorrect.

Option C can not represent the solution, therefore option C is correct.
