Answer: Choice [D] - "power of a power" ✅
Step-by-step explanation:
Hii, do you need to know which law you should use to simplify ?
No problem!
The law we will use here is "power of a power".
What "power of powers" means is we raise a power to a power, which is exactly what we do here: We raise x^4 to the power of 9. To simplify our expression, we multiply the powers. ()
So the right answer is: Choice [D] - "Power of a power"
The simplified answer is
Voila! There's our answer, cheers!

If 0.4 kg cost 4. 0 dollar
than 1.kg will cost x dollar
x = (1 * 4)/0.4 = 10 dollars
1 kg tomatoes cost 10 dollars
This is really a long way to go to make something complicated
out of something simple. The last choice does the job.
cos(180) = -1
sin(180) = 0
So 4 [cos(180) + i sin(180) ]
= 4 [ -1 + i (0) ]
= -4 yay!
Answer:
£503.75
Step-by-step explanation:
Andy is buying a car.
Step 1
We calculate the decrease
He negotiated a 7% decrease on a £6 500 car.
Decrease = 7% × £6500
= $455
Step 2
We calculate the new price of the car.
= Old price - Decrease
= £6500 - £455
= £6045
Step 3
We calculate the amount he pays every month.
We are told that:
He will pay the full balance in 12 equal monthly payments.
Andy's monthly payments =
New price/12 months
= £6045/12
= £503.75
Therefore, the amount he would be paying each new month = £503.75
The equation representing the cost in The Free Press is 12 + 5d.
<h3>How to depict the equation?</h3>
The equation representing the cost in The Free Press will be:
= 12 + (5 × d)
= 12 + 5d
The equation representing the cost in The Banner will be:
= 8 × d
= 8d
The table of value for Free Press will be:
1st day = 12
2nd day = 17
3rd day = 22
4th day = 27
5th day = 32
The table of value for the Banner will be:
1st day = 8
2nd day = 16
3rd day = 24
4th day = 32
5th day = 40
The newspaper that will be used to run the advertisement for the first day is Free Press since it's cheaper.
The newspaper that will be used to run the advertisement for twelve days will be:
Free press = 12 + 5d
= 12 + 5(12)
= 12 + 60 = 72
The banner = 8d = 8 × 12 = 96
Therefore, for 12 days, Free Press is cheaper.
