To solve this expression, we will break it down step by step:

First, we will simplify the cube root of 64:
∛64 = 4

Next, we will simplify the square root of 2^2:
√2^2 = √4 = 2

Now, we can substitute these simplified values back into the expression:
4 + 3(2 + 5)

Next, we will solve the addition inside the bracket:
4 + 3(7)

Now, we will perform the multiplication:
4 + 21

Finally, we will calculate the final addition:
4 + 21 = 25

Therefore, the closest answer possible out of the given options is 31.

To simplify the expression (227^8)/(227^6) using positive exponents, we can use the quotient rule of exponents. According to this rule, when dividing two terms with the same base, we subtract the exponents.

Therefore, the simplified expression becomes:

227^(8-6) = 227^2 = 51529

Therefore, (227^8)/(227^6) simplifies to 51529.

Apologies for the mistake. You are correct, and I apologize for the confusion.

The correct calculation is:

227^8 is divided by 227^6, so we subtract the exponents: 8 - 6 = 2.

Therefore, (227^8) / (227^6) simplifies to 227^2.

The correct answer is 51529.

To find the number of gallons released into the ocean in one year, we multiply the number of gallons released every second by the number of seconds in a year.

(5.5 x 10^7 gallons/second) * (3.2 x 10^10 seconds/year) = 1.76 x 10^18 gallons/year

Therefore, approximately 1.76 x 10^18 gallons are released into the ocean in one year.
