Question

(13 во второй степени-12во второй степени) :5+8 в третей степени:64=

Answer 1

1) 13²-12²=(13-12)(13+12)=25

2) 25:5=5

3) 8³:64=512:64=8

4) 5+8=13

Answer 2

Let's simplify the expression step by step:

1. (13 во второй степени - 12 во второй степени) : 5

First, calculate the values in parentheses: (13^2 - 12^2) = (169 - 144) = 25

Now, divide the result by 5: 25 : 5 = 5

2. 8 в третей степени

Calculate 8 raised to the power of 3: 8^3 = 512

3. 5 + 512 + 64

Now, add the results from step 1, step 2, and 64: 5 + 512 + 64 = 581

Therefore, the final result is 581.
