Answer:
<h2>35 -10√10 + 14√6 - 8√15</h2>
Step-by-step explanation:
(√2 + √3)² · (√5 - √2)²
use (a ± b)² = a² ± 2ab + b²
= [(√2)² + 2(√2)(√3) + (√3)²] · [(√5)² - 2(√5)(√2) + (√2)²]
= (2 + 2√6 + 3) · (5 - 2√10 + 2)
= (5 + 2√6)(7 - 2√10)
use FOIL: (a + b)(c + d) = ac + ad + bc + bd
= (5)(7) + (5)(-2√10) + (2√6)(7) + (2√6)(-2√10)
= 35 - 10√10 + 14√6 - 4√60
= 35 - 10√10 + 14√6 - 4√(4 · 15)
= 35 - 10√10 + 14√6 - 4 · √4 · √15
= 35 -10√10 + 14√6 - 4 · 2 · √15
= 35 -10√10 + 14√6 - 8√15
Answer:
20-7.5 = 12.5
115- 12.5% = 100.625
