Step-by-step explanation:
Seventeen and fifty thousandths in stander form is this:
<em><u>17.05</u></em>
Answer:
0.332
Step-by-step explanation:
given series
1/4, 1/16,1/64.1/256
this is geometric series
where common ratio r is given by
nth term/ (n-1)th term
let the second term is nth term and first term is (n-1)th term
r = 1/16 / (1/4) = 1/4
___________________________________________
sum of series is given by
a (1-r^n)/1-r
where a is first term
n is the number of terms
r is the common ration
___________________________________________
in the given series
1/4, 1/16,1/64.1/256
a = 1/4
r = 1/4
n = 4
thus ,
sum = 1/4(1-(1/4)^4)/ (1-1/4)
sum = 1/4(1-(1/256)/(4-1)/4
sum = 1/4((256-1)/256 / 3/4
1/4 in numerator and denominator gets cancelled
sum =( 255/256*3) = 255/768 = 0.332
Thus, sum of series is 0.332.
It's an irrational number, so you can get as close as you need to, but
you can't write it exactly with numbers. As a decimal, it never ends.
-- The number <em>5.4175</em> is within 0.00003% of the actual value.
-- (5.4175)³ is less than 0.000084% smaller than 159 .
