Answer:
Step-by-step explanation:
the bar above 36 means that the digits 36 are being repeated
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.13636.. ( multiply both sides by 10 and 1000 )
10x = 1.3636... (1)
1000x = 136.3636... (2)
subtract (1) from (2) thus eliminating the repeating digits
990x = 135 ( divide both sides by 990 )
x = 
= ← in simplest form
You're looking for the time
that it takes for the principal
to double, so
. Dividing both sides of the formula by
leaves you with
You're given that the account earns 0.75% interest and that the interest is compounded monthly, so
and
.

The product is 10√14 +8√21 +30√3 +36√2
Step-by-step explanation:
Given the question as;
( 2√7 +3√6)(5√2+4√3)
Distribute
2√7(5√2+4√3) + 3√6 (5√2+4√3)
open brackets
2√7 × 5√2 + 2√7 × 4√3 + 3√6×5√2+3√6×4√3
2×5×√7×√2 + 2×4×√7×√3+3×5×√6×√2 + 3×4×√6×√3
10×√14 +8√21+15√12+12√18-----------------------------simplify √12 and √18 further
10√14+ 8√21 + 15×√4×√3 + 12×√9×√2
10√14 +8√21 +15×2×√3 + 12×3×√2
10√14 +8√21 +30√3 +36√2
