Question

Вычислите число Y по формуле Y=X:500, где X=2028. Для полученного числа Y найдите мантиссу и порядок.

Answer 1

Y = 2028÷500 = 4,056 = 0,4056 * 10¹

Ответ: Мантисса = 0,4056

Порядок = 1

Answer 2

Let's break down the given equation step by step:

(7 + 4)³ = 11³

= 11 × 11 × 11

= 1331

Now, let's evaluate the second part of the equation:

5² + 4² = 25 + 16

= 41

Therefore, the equation (7+4)³ = 5² + 4² is not true.

It seems there might be a mistake in the equation you provided. If you meant something else or if you have any further questions, please let me know!
