So 17 out of 30 or 17/30
so we want to find the equivilent of 17/30 with the bottom number 300 so

we know that 1/2=4/8 because 1/2 times 4/4 ( or 1) =4/8 soo

we notice that 300 is 10 times of 30 so

17/30 times 10/10=170/300 so

We know that 30 students have 17 dogs. If we want to know how many dogs will have 10 times more students (300) we can miltiply 17 times 10 as well to get the answer.
17*10=170 - its predicted value

What is the factorization of 729^15+1000​
Nesterboy [21]

\bf \textit{difference and sum of cubes} \\\\ a^3+b^3 = (a+b)(a^2-ab+b^2) \\\\ a^3-b^3 = (a-b)(a^2+ab+b^2) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \begin{cases} 729=27^2\\ \qquad (3^3)^2\\ 1000=10^3 \end{cases}\implies 729^{15}+1000\implies ((3^3)^2)^{15}+10^3 \\\\\\ ((3^2)^{15})^3+10^3\implies (3^{30})^3+10^3\implies (3^{30}+10)~~[(3^{30})^2-(3^{30})(10)+10^2] \\\\\\ (3^{30})^3+10^3\implies (3^{30}+10)~~~~[(3^{60})-(3^{30})(10)+10^2]

now, we could expand them, but there's no need, since it's just factoring.
