Vilka [71]

Answer:

________________________________

step\:1

\frac{1}{ \sqrt{3} -  \sqrt{2}  }

write the equation

________________________________

step\:2

\frac{1 \times ( \sqrt{3} +  \sqrt{2})  }{ (\sqrt{3} -  \sqrt{2} ) \times  (\sqrt{3}  +  \sqrt{2})  }

multiply both numerator and denominator by √3+√2

________________________________

step\:3

\frac{ \sqrt{3} +  \sqrt{2}  }{ ( 3 ) - ( 2 ) }

after multiplying numerator with √3+√2 we get→√3+√2

after multiplying denominator we get 3-2

________________________________

step\:4

\frac{ \sqrt{3}  +  \sqrt{2} }{1}

after subtracting 3 with 2 we get →1

________________________________

hence denominater is rationalized✓

hope it helped you:)

Two- thirds of a number added to itself is 20. what is the number?
MrRissso [65]

Equation

Let the number = x

(2/3)x + x = 20                   Change the x to thirds.

(2/3)x + 3/3x = 20              3/3 = 1 Now  combine the like terms.

(2 + 3)/3 = 20                     2/3 + 3/3 = 5/3  

(5/3) x = 20                        Multiply both sides by 3/5

(5/3)*(3/5)x = 20*3/5        Complete the multiplication on the right

x = 4 * 3                            Combine

x = 12                                 Answer
