Final answer:
Option 1 is correct.The statement about the C# ^ operator being used for exponentiation is false. In C#, ^ is a bitwise XOR operator and Math.Pow is used for exponentiation. In scientific notation, squaring exponentials involves squaring the digit term and doubling the exponent.
Step-by-step explanation:
The C# operator ^ is not used for exponentiation; the statement is false. In C#, the ^ operator is actually the bitwise exclusive OR (XOR) operator. For exponentiation, you would typically use the Math.Pow method, which raises a number to the power of another number. For example, to calculate 2 raised to the power of 3, you would use Math.Pow(2, 3), which would give you the result of 8.
When dealing with exponentials in scientific notation, one must carefully apply the exponent rules. For instance, in scientific notation 1.6 × 10² is equivalent to 160, since the decimal is moved two places to the right. With negative exponents such as 2.4 x 10^-2, the decimal is moved two places to the left, resulting in 0.024.
Exponential terms, like those found in scientific notation, can be squared by squaring the digit term as usual and then multiplying the exponent by 2. For example, squaring 3 x 10^2 would involve squaring 3 to get 9 and then multiplying the exponent by 2 to get 9 x 10^4.
