$(x+5)^2=49$
squaer root both sides
x+5=+/-7
minus 5 both sides
x=-5+/-7
x=-5+7=2
x=-5-7=-12

x=2 or -12

Answer:

$\frac{(3x)^{12} }{(3x)^{4} } =(3x)^{8}$

Step-by-step explanation:

As we are dividing by powers, we can just subtract the powers as they have the same base. As 12-4=8 the answer would be

$\frac{(3x)^{12} }{(3x)^{4} } =(3x)^{8}$
