Answer: (7/2)^2
Step-by-step explanation:
The prove that the equation can be verified using the laws of exponents.
<h3>What is the proof of the equation given; 2^(2x+4)= 16 × 2^(2x)?</h3>
It follows from the task content that the equation given is; 2^(2x+4)= 16 • 2^(2x).
It follows from the laws of indices ; particularly, the product of same base numbers.
The evaluation is therefore as follows;
2^(2x+4)= 16 • 2^(2x)
2^(2x) • 2⁴ = 16 • 2^(2x)
2^(2x) • 16 = 16 • 2^(2x)
Hence, since LHS = RHS, it follows that the expression is mathematically correct.

Answer:
$15.71
Step-by-step explanation:
They have already raised $218.25.
$483.62 - $218.25 = $265.37 left to raise
There are 17 students, so the remaining amount can be divided between them.
$265.37 ÷ 17 students = $15.71 that each student needs to raise
You can check this by multiplying $15.71 by 17.
