for
x^m=y
that means
$log_x(y)=m$
so

$7^{x+4}=-34$ means

$log_7(-34)=x+4$
minus 4 from both sides
$log_7(-34)-4=x$

Answer:

xy = - 27

Step-by-step explanation:

Note that

(x - y)² = x² - 2xy + y² ← substitute given values, that is

9² = 27 - 2xy

81 = 27 - 2xy ( subtract 27 from both sides )

54 = - 2xy (divide both sides by - 2 )

- 27 = xy
