Question

> < или = 8×9-8×3 8×(9-3); 6×5-4×5 6×(5-3)

Answer 1

8*9-8*9  = 8*(9-3)
6*5-4*5  < 6*(5-3)

Answer 2

To solve these expressions, we need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). PEMDAS tells us to perform operations inside parentheses first, then exponents, then multiplication and division (from left to right), and finally addition and subtraction (from left to right).

Let's apply PEMDAS to each of the expressions:

1. <

To compare < or >, we need to simplify each side of the expression first:

8×9-8×3 = 8×(9-3) = 8×6 = 48 8×(9-3) = 8×6 = 48

Both sides of the expression simplify to 48, so they are equal. Therefore, 8×9-8×3 < 8×(9-3) is false.

2. >

To compare < or >, we need to simplify each side of the expression first:

6×5-4×5 = 2×5 = 10 6×(5-3) = 6×2 = 12

The left side of the expression simplifies to 10, while the right side simplifies to 12. Therefore, 6×(5-3) > 6×5-4×5 is true.

So the final answer is:

8×9-8×3 < 8×(9-3); False 6×(5-3) > 6×5-4×5; True
