Question

6÷2(1+2)=?какой ответ правильно?

Answer 1

Ответ 9 вроде как, надеюсь что так

Answer 2

6:2(1+2) = 9

1) 1+2=3

2)6:2=3

3) 3 • 3 = 9

Answer 3

The expression 6÷2(1+2) can be interpreted in different ways depending on the rules of mathematical precedence that you apply. This type of expression is often considered ambiguous, and that's why it's essential to follow a specific set of rules to solve it correctly.

One common approach is to use the BODMAS or PEMDAS rule, which stands for:

BODMAS: B - Brackets first O - Orders (i.e., exponents and roots, etc.) D - Division and M - Multiplication (from left to right) A - Addition and S - Subtraction (from left to right)

PEMDAS (same as BODMAS, but the order of D and M is reversed): P - Parentheses first E - Exponents (i.e., orders and roots) MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

So, applying the PEMDAS rule to the expression:

6 ÷ 2(1+2)

1. Parentheses first: 1+2 = 3
2. Division and Multiplication (from left to right): 6 ÷ 2 * 3

Now, 6 ÷ 2 equals 3, so the expression becomes:

3 * 3 = 9

So, according to the PEMDAS rule, the answer is 9.

However, it's essential to note that different people or math conventions may interpret the expression differently, and in some cases, it may be considered ambiguous and require clarification to get the intended result. To avoid confusion, it's best to use parentheses to explicitly state the intended order of operations.
