Answer:

Step-by-step explanation:
Rewrite the equation using the next propierties:




Cancel logarithms by taking exp of both sides:

Divide both sides by 4:

Take the square root of both sides:

<span>We have a right angled triangle with an opposite of 300.5 ft. (306 - 5.5) and an adjacent of 400 ft. Recalling SOH CAH TOA, tanθ = O/A.
tan(θ) = 300.5/400.
θ = tan^-1(300.5/400).
θ = 36.9°.</span>
(13 + 47) (21 + 79) =
60 + 100 =
160
Answer:
x = 2
Step-by-step explanation:
note that 4096 =
, then
= 
Since bases on both sides are equal, both 8 , then equate the exponents
2x = 4 ( divide both sides by 2 )
x = 2
