Answer:

1) Taking 10xy we get

=10xy(x^4-4y^2)

2) Taking ab common

=ab(a^4-64)

3) Taking 2 common

=2(125m^3+27)

4) k^4-10k^2-39

=k^4-13k^2+3k^2-39

=k^2(k^2-13)+3(k^2-13)

=(k^2+3)(k^2-13)

5) 4w^4+10w^2+6w^2+15

=2w^2(2w^2+5)+3(2w^2+5)

=(2w^2+5)(2w^2+3)

6) 2n^3+7n^2-2n-7

=n^2(2n+7)-1(2n+7)

=(n^2-1)(2n+7)

Hope this helps

Answer:

${10}^{th} \: term = \frac{5}{512}$

Step-by-step explanation:

geometric progression formula:

${n}^{th} \: term = ar ^{n - 1}$

given:

common ratio, r = 1/2

$first \: term \: = 5$

1) find the value of a

${n}^{th} \: term \: = a {r}^{n - 1}$

we're finding the 1st term, so substitute 1 into n:

${1}^{st} \: term = a( \frac{1}{2} ) {}^{1 - 1}$

first term is 5. so we substitute 5 into the equation:

$5 = a(1)$

$a = 5$

2) find the 10th term

we're finding the 10th term, so substitute 10 into the equation and don't forget to substitute 5 into a:

${10}^{th} \: term = 5( \frac{1}{2} ) {}^{10 - 1}$

${10}^{th} \: term = 5( \frac{1}{512} )$

${10}^{th} \: term = \frac{5}{512}$
