Derek and Donovan were trying to solve the equation 4^4=16^x. Derek had an idea.
-"I know," he said. “Isn't 16 equal to 4^2?"
"Yeah, so what?" said Donovan.
“That means that we can rewrite the equation to look
like 4^4=(4^2)^x. This is much easier to solve!" replied
Derek.
"Yes," said Donovan. "That makes sense. Isn't there another way, too? Since 4 is the same as 2^2 and 16 is the same as 2^4, can't we rewrite it
as (2^2)^4=(2^4)^x?"

1. Use both methods to solve 4^4=16^x.

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
