Step-by-step explanation:
Given that,
a + 2b = 17
Also,
2a + b = 4
By adding the above expressions we get,
a + 2b + 2a + b = 17 + 4
3a + 3b = 21.
3 (a + b) = 21
a + b = 21/3
a + b = 7 Let us take 'b' = 10
a + 10 = 7
a = 7 - 10
a = -3
Now let's check by verifying by putting a = -3 and b = 10 in the previous expressions
a + 2b = 17
-3 + (2 × 10) = 17
-3 + 20 = 17
17 = 17
2a + b = 4
(2 × -3) + 10 = 4
-6 + 10 = 4
4 = 4
Therefore, a = -3 and b = 10 [(-3,10)] is the solution.
You can solve this by using 8!
when you put this through a calculator, you'll get 40320.
Therefore, eight boxes can be arranged in 40,320 different ways on a shelf.
Hope that helps :)
Answer: Product of powers

The product of powers rules basically says that two powers, let's call them

and

, with the same base (a) multiplied together equals

.
In your problem you can see that

and

are being multiplied together and the exponents are being added, which is what the "product of powers" law says.
