Question

Solve the radical equation $square root of 2 x end root equals 12$ . Check for extraneous solutions

hint Hint:

Rearrange the equation and then solve for x.

The correct answer is: 12

Complete step by step solution:
Here we have the equation $square root of 2 x end root equals 12$
On squaring, we have $2 x equals 12 squared$
⇒ 2x = 144
⇒ x = 72
On substituting the value of x in the equation, we get
$square root of 2 cross times 72 end root equals square root of 144 equals 12$
Hence there is no extraneous solution.

Escape velocity is the velocity at which an object must be travelling to leave a star or planet without falling back to its surface or into orbit. Escape Velocity V depends on the gravitational constant G , the mass M, and radius r, of the star or planet .
$V equals square root of fraction numerator 2 G M over denominator r end fraction end root$
Rewrite the equation to solve for mass,
The escape velocity of earth is 11, 200 m/s and its radius is 6,371,000 m. The gravitational constant is 6.67x 10^-11. What is the earth's mass in kilograms?
