$\frac{a^{12}b^{8}}{a^{2}b^{4}}$

remember
(ab)/(cd)=a/c times b/d

also $\frac{x^{m}}{x^{n}}= x^{m-n}$

split it up with like terms

$\frac{a^{12}}{a^{2}}$ times $\frac{b^{8}}{b^{4}}$

do subtraction
for a's
12-2=10

b's
8-4=4

answe is $a^{10}b^{4}$

first one

What are the chances of flipping a coin 12 times and it landing on heads 11 times?

12 flips, 11 heads, 1 tails
Let's say there's a 50-50 chance of landing heads.
There are 12 flips and 12 specific outcomes.
The probability is 2^(-12) = 1/4096 = 0.0244%

If the last flip doesn't matter, then the probability would be 2^(-11) = 1/2048 = 0.0488%.

Have an awesome day! :)

Zepler [3.9K]

after 1 year he will get : 800 + 800 x 3,5% = 800 x 1,035 = $828

after 2 years he will get : 828 x 1,035 = 800 x 1,035 x 1,035 = 800 x 1,035²

after n years he will get : 800 x 1,035ⁿ
