Simplify the expression<br> (-3+4k) - (-2+ 7k)

DedPeter [7]

Answer: −1−3k

Step-by-step explanation:

Distribute:

(−3+4k)−1(−2+7k)

(-3+4k)+{2-7k}

Eliminate redundant parentheses:

(−3+4k)+2−7k

-3+4k+2-7k

Add the numbers:

−3+4k+2−7k

−1+4k−7k

Add the same term to both sides of the equation:

−1+4k−7k

−1−3k

How can I express logbx-(logby+logbz) as a single log?

GuDViN [60]

$\bf log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)
\\ \quad \\
% Logarithm of rationals
log_{{ a}}\left( \frac{x}{y}\right)\implies log_{{ a}}(x)-log_{{ a}}(y)\\\\
-----------------------------\\\\
log_b(x)-[log_b(y)+log_b(z)]\implies log_b(x)-[log_b(yz)]
\\\\\\
log_b\left( \cfrac{x}{yz} \right)$
