2 / 15

This is simpler than you think. Just take the square root of the denominator and of the numerator and stick it back into fraction form. The square root of 4 is 2 and the square root of 225 is 15. Voila: 2 / 15.

Find the interval of convergence of the power series. (Be sure to include a check for convergence at the endpoints of the interv

Anon25 [30]

I'm guessing the power series given is

$\displaystyle \sum_{n=1}^\infty (-1)^{n+1}\frac{(x-8)^n}{8^n}$

which you can condense somewhat into

$\displaystyle -\sum_{n=1}^\infty \left(\frac{8-x}8\right)^n$

You should recognize this as a geometric series, which converges for

$\left|\dfrac{8-x}8\right|$

Guys, please help me with problem.

likoan [24]

Answer:

$\boxed{\bold{-25}}$

Step-by-step explanation:

Remove parenthesis: (a) = a

$\bold{\frac{-5^2+10^2}{-2\cdot \:5\cdot \:3+3^3}}$

$\bold{-5^2+10^2: \ 75}$

$\bold{\frac{75}{-2\cdot \:5\cdot \:3+3^3}}$

$\bold{-2\cdot \:5\cdot \:3+3^3: \ -3}$

$\bold{\frac{75}{-3}}$

Apply fraction rule: $\bold{\frac{a}{-b}=-\frac{a}{b}}$

$\bold{-\frac{75}{3}}$

Divide $\bold{\:\frac{75}{3}: \ 25}$

$\bold{-25}$
