Question

Explain details.

Answer 1

To express the given expression, 2 x 3² x 7, as a whole number, you have to follow the order of operations, which is often remembered by the acronym PEMDAS:

- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)

Starting with the given expression:

2 x 3² x 7

First, you should handle the exponent:

3² = 3 x 3 = 9

Now, replace the exponent part of the expression with its value:

2 x 9 x 7

Proceed with multiplication from left to right:

First, multiply 2 and 9:

2 x 9 = 18

Now, you're left with:

18 x 7

Finally, multiply 18 and 7:

18 x 7 = 126

So the expression 2 x 3² x 7 equals 126 when represented as a whole number.
