## Section8.5Complex Solutions to Quadratic Equations
### Subsection8.5.1Imaginary Numbers
Let's look at how to simplify a square root that has a negative radicand. Remember that $\sqrt{16}=4$ because $4^2=16\text{.}$ So what could $\sqrt{-16}$ be equal to? There is no real number that we can square to get $-16\text{... |

# Scientific notation
Scientific notation is a form of presenting very large numbers or very small numbers in a simpler form. As we know, the whole numbers can be extended till infinity, but we cannot write such huge numbers on a piece of paper. Also, the numbers which are present at the millions place after the decim... |
# Algebra problem regarding system of logarithmic equations.
The equations are:
$\log_{4}(x)+\log_{4}(y)=5$
$\big(\log_{4}(x)\big)\big(\log_{4}(y)\big)=6$
I attempted to solve this problem by solving the pair of equations for $x$.
For the first equation:
$\Longrightarrow \log_{4}(xy)=5 \Longrightarrow xy=4^{5} \L... |
