Solve the Basic Multiplication: 10×10 = ?

To solve this problem, let’s follow the outlined steps:

• Step 1: Calculate $10 \times 10$.
• Step 2: Express the calculation using exponent rules.
• Step 3: Verify the possible expressions match the given choices.

Now, let's work through each step:
Step 1: The direct multiplication of 10 by 10 yields $100$ because $10 \times 10 = 100$.
Step 2: We can express this calculation using the rules of exponents. Since both numbers are 10 and multiplied together: $10^1 \times 10^1 = 10^{1+1} = 10^2$.
Step 3: We consider the following expressions given in the multiple-choice answers:
- Choice 1: $10^{1+1}$ equals $10^2$.
- Choice 2: $10^2$ equals 100.
- Choice 3: 100 is the result of the direct multiplication.

Each choice is consistent with the others through these steps. Thus, all the provided expressions—$10^{1+1}$, $10^2$, and 100—accurately represent the resolved equation $10 \times 10$.

Therefore, the solution to the problem is All answers are correct.
