Question

10×(3²-1²)=9²+(7²-15)​

Answer 1

Ответ:

10×(3²-1²)=10×8=80

9²+(7²-15)=115

Answer 2

Равно: 115 ,но это не точно

Answer 3

Let's solve the equation step by step:

1. First, calculate the values inside the parentheses: 3² = 9 1² = 1

2. Subtract 1² from 3²: 9 - 1 = 8

3. Now, calculate the values on the right side of the equation: 7² = 49 15 - 49 = -34

4. Now, rewrite the equation with the calculated values: 10 * 8 = 9² + (-34)

5. Calculate the values on both sides of the equation: 10 * 8 = 80 9² = 81

6. Rewrite the equation: 80 = 81 + (-34)

7. Add 81 and -34: 80 = 47

So, the equation 10×(3²-1²)=9²+(7²-15) is not true because 80 does not equal 47. There seems to be an error in the equation.
