Note: √a * √a = a
√a * √b = √ab
(√2 + √10)² = (√2 + √10)(√2 + √10)
= √2(√2 + √10) + √10(√2 + √10)
= √2*√2 + √2*√10 + √10*√2 + √10*√10
= 2 + √20 + √20 + 10
= (2 + 10) + (√20 + √20)
= 12 + 2√20
√20 = √(4 *5) = √4 * √5 = 2√5
= 12 + 2√20 = 12 + 2(2√5)
= 12 + 4√5

Answer:
$8825.10
Step-by-step explanation:
Interest total= P x r x t
P = principal amount, or $6900
r= interest rate, or 0.031
t = time, or 9 years
6900 x 0.031 x 9 = 1925.10
You now add this to the original amount
6900 + 1925.10 = $8825.10
Answer:
72
Step-by-step explanation:
