Question

(7/4)³•(4/7)²и (-2)⁰

Answer 1

Ответ:

(49/16)•(16/49)=49•16/49•16(сокращаем 16 и 16, 49 и 49)=1²=1

(-2)⁰=1

Answer 2

Let's break down the expression step by step:

1. (7/4)³ = (343/64)
2. (4/7)² = (16/49)
3. (-2)⁰ = 1 (Any non-zero number raised to the power of 0 is 1)

Now, let's multiply these results together:

(343/64) * (16/49) * 1 = (343 * 16) / (64 * 49) = 54928 / 3136 = 17.5

So, the final result of the expression is approximately 17.5.
