Daniel is using logarithms to solve the equation 2^4x = 14. Which of the following equations would be equivalent to his original

ycow [4]

Remember
$log_a(b^c)=(c)log_a(b)$
so
$2^{4x}=14$ take the log of both sides
$log(2^{4x})=log(14)$ or
$4xlog(2)=log(14)$

B is the answer

Simplify the expression. Write your answer as a complex number.

prohojiy [21]

Answer:

$15-8i$

Step-by-step explanation:

we know that

The algebraic expression is equal to

$5\sqrt{9}-\sqrt{-64}}$

Remember that

$\sqrt{9}=3$

and

$i=\sqrt{-1}$

so

$\sqrt{-64}=i\sqrt{64}=8i$

substitute

$5\sqrt{9}-\sqrt{-64}}=5(3)-(8i)=15-8i$

Find the power series expansion for f(x)= 4/(x+2); x doesn't equal 2, centered at 0

suter [353]

$\dfrac4{x+2}=\dfrac2{1-\left(-\frac x2\right)}=2\displaystyle\sum_{n\ge0}\left(-\frac x2\right)^n$

which is valid for $\left|-\dfrac x2\right|$ , or $|x|$ .
