Question

А) 8+7^2,(8+7)^2.,8^2+7^2​

Answer 1

Ответ:

Объяснение:

8+7²=8+49=57

(8+7)²=15²=225

8²+7²=64+49=113

Answer 2

Let's solve the expressions step by step:

А) 8 + 7^2 This expression involves exponentiation and addition. To solve it, we first calculate 7^2 (7 raised to the power of 2), which is 49. Then we add 8 to it:

8 + 7^2 = 8 + 49 = 57

B) (8 + 7)^2 This expression involves addition and then squaring the result. To solve it, we first perform the addition inside the parentheses:

(8 + 7) = 15

Now, we square the result:

(8 + 7)^2 = 15^2 = 225

C) 8^2 + 7^2 This expression involves two separate squares: 8^2 (8 raised to the power of 2) and 7^2 (7 raised to the power of 2). We calculate each of them and then add them together:

8^2 = 8 * 8 = 64 7^2 = 7 * 7 = 49

Now, we add both results:

8^2 + 7^2 = 64 + 49 = 113

So, the final values for each expression are: A) 8 + 7^2 = 57 B) (8 + 7)^2 = 225 C) 8^2 + 7^2 = 113
