Question

rationalize the denominator

Answer 1

Step-by-step explanation:

1/4+2√3 x 4-√3/4-√3

=4-2√3/4²-(2√3)²

4-2√3/16-12

=4-2√3/4

Answer 2

Answer:

Step-by-step explanation: 1/(4+2√3)=(1)(4-2√3)/(4+2√3)(4-2√3)

=(4-2√3)/(4+2√3)(4-2√3)

=(4-2√3)/(4²-8√3+8√3-4(3)

=(4-2√3)/(4²-12)

=(4-2√3)/(16-12)

=(4-2√3)/4

=(4/4)-(2√3/4)

=1-(√3/2)

=(2-√3)/2
