Answer 1

516 будет, или обьяснение надо?

Answer 2

To evaluate the expression 4^3 * 12^2 + 7^3 - 15^3, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, let's calculate the exponents:

4^3 = 4 * 4 * 4 = 64 12^2 = 12 * 12 = 144 7^3 = 7 * 7 * 7 = 343 15^3 = 15 * 15 * 15 = 3375

Now we substitute these values back into the expression:

64 * 144 + 343 - 3375

Next, let's perform the multiplication:

64 * 144 = 9216

Substituting this value back into the expression:

9216 + 343 - 3375

Finally, let's perform the addition and subtraction:

9216 + 343 = 9559 9559 - 3375 = 6184

Therefore, the expression 4^3 * 12^2 + 7^3 - 15^3 is equal to 6184.
