Express 2 x 3² x 7 as a whole number. Responses are 126 126 252 252 42 42 63
Explain details.
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.
