<h3>Answer:</h3>
∛135 = 3∛5
<h3>
Explanation:</h3>
∛135 = ∛(27×5) = ∛27 × ∛5 = 3∛5
As with any root, the root of a product is the product of the roots of the factors. Here, the only cubic factor is 27 = 3³.

It can help immensely if you are familiar with the squares and cubes of small integers. Of course, your knowledge of regular times tables will get you to the fact that ...
... 27 = 3·9 = 3·3·3 = 3³
Knowledge of divisibility rules is helpful, too. Here, you can see that 135 ends in 5, so you know that 5 is a factor of the number.
Answer:
A) i = $4488.75
B) Amount paid per month = $785.45
Step-by-step explanation:
A) Formula for simple interest is;
i = PRT
We are given;
Principal; P = $28500
Rate; R = 4.5% = 0.045
Time; T = 42 months = 42/12 years
Thus;
i = (28500 × 0.045 × (42/12))
i = $4488.75
B) Since interest was $4488.75 and principal is $28500,then total he paid after 42 months is;
Total = 28500 + 4488.75
Total = $32988.75
Amount paid per month = 32988.75/42 = $785.45
It is 5.05.
Hoped this helped.
