Question

simplify each of the following by rationalizing the denominator 2 sqrt 3- sqrt 5 / 2 sqrt 2 + 3 sqrt 3​

Answer 1

Answer:

2^3-3^5/2^2+3^3

= (2^3-3^5) (2^2-3^3)/2^2+3^3 (2^2-3^3)

=(8-243)(4-9) / (4+9)×( 4-9)

=235×-5/13×-5

= 18.7

Answer 2

Answer:

(2√10+18) - (4√6+3√15) /19

Step-by-step explanation:

2√3-5 / 2√2+3√3 × 2√2-3√3 / 2√2-3√3

4√6-2√10-6×3+3√5 / 8-27

4√6-2√10-18+3√15 / -19

(2√10+18) - (4√6+3√15) / 19
