7-73.

Given that $\text{log}_{x}\left(2\right) = a, \text{log}_{x}\left(5\right) = b, \text{and log}_{x}\left(7\right) = c$, write expressions using $a, b$, and/or $c$ for each log expression below.

1. $\operatorname { log } _ { x } (10)$

$\log_{x}(2\cdot5)$

$\log_{x}(2)+\log_{x}(5)$

$a + b$

1. $\text{log}_{x}\left(49\right)$

$2c$

1. $\operatorname { log } _ { x } (50)$

1. $\text{log} _ { x } (56)$

$3a + c$
