Question

Найдите значения выражений(7*7)/(5*5+6*4)-(9-9)*3, 40/(24/6)+7*(12-2*2)-5*5 (3КЛАСС)

Answer 1

(7*)/(5*5+6*4)-(9-9)*3 = 7 / 49 - 0 = 0,7
40/(24/6) + 7*(12-2*2)-5*5=40/4 + 56 - 25 = 10+56 - 25 = 66-25 = 41

Answer 2

Calculating the Expressions

Let's calculate the given expressions step by step:

1. (7*7)/(5*5+6*4)-(9-9)*3 2. 40/(24/6)+7*(12-2*2)-5*5+(3КЛАСС)

Calculation Steps

1. (7*7)/(5*5+6*4)-(9-9)*3 - First, calculate the values inside the parentheses: - 7*7 = 49 - 5*5 = 25 - 6*4 = 24 - Then, perform the addition and subtraction inside the parentheses: - 25 + 24 = 49 - 49 - 49 = 0 - Now, perform the division and multiplication: - 49/0 is undefined - (9-9)*3 = 0

2. 40/(24/6)+7*(12-2*2)-5*5+(3КЛАСС) - First, calculate the value inside the parentheses: - 24/6 = 4 - 12-2*2 = 8 - Then, perform the multiplication and subtraction inside the parentheses: - 7*8 = 56 - 5*5 = 25 - Now, perform the division and addition: - 40/4 = 10 - 10 + 56 = 66 - 66 - 25 = 41

Results

1. The result of the first expression is undefined. 2. The result of the second expression is 41.

These are the calculated results for the given expressions.
