The correct answer is 81 because when you multiply 9 by 9, you get the product of 81.

To find the sum of 257 and 234, we add the corresponding digits of each number starting from the right. 7+4=11, so we write down 1 and carry over the 1. 5+3+1=9, so we write down 9. Finally, 2+2+1=5, so we write down 5. Therefore, the sum of 257 and 234 is 491.

The given question is a subtraction problem. When we subtract 77 from 4, we get a negative number because 77 is greater than 4. The correct answer is -73.

The given answer, 44x44, is the result of multiplying 44 by itself. In other words, it is the square of 44. This can be determined by multiplying the two numbers together, resulting in 1936.

The number 11 is not a multiple of 3 because it cannot be divided evenly by 3. A multiple of 3 is any number that can be obtained by multiplying 3 by an integer. In this case, 11 cannot be obtained by multiplying 3 by any integer, so it is not a multiple of 3.

The equation 11x[y] = 121 can be solved by dividing both sides of the equation by 11. This gives us [y] = 11. Since the only option that equals 11 is 12, the correct answer is 12.

The correct answer is 2-4 because subtracting 8 from 4 gives us -4, which is the same as subtracting 4 from 2. Therefore, 2-4 is the correct answer.

The given equation is 4=4=, and the options are 44 and 24. The correct answer is 44 because the equal sign (=) is often used to represent "is equal to." Therefore, the equation can be read as "4 is equal to 4 is equal to something." The only option that satisfies this condition is 44, where both 4's are equal to each other.

The given sequence is a series of numbers where each number is obtained by multiplying the previous number by 10. Starting with 1, we get 1 x 10 = 10, 10 x 10 = 100, 100 x 10 = 1000, and so on. The final number in the sequence is obtained by multiplying the previous number (100000) by 10, resulting in 1000000.

To solve the expression 4+6−8×9+6−10+504+6−8×9+6−10+50, follow the order of operations (PEMDAS/BODMAS):

Perform multiplication: 8×9=728×9=72

Substitute this result back into the original expression: 4+6−72+6−10+504+6−72+6−10+50

Perform the addition and subtraction from left to right: (4+6)−72+6−10+50=10−72+6−10+50(4+6)−72+6−10+50=10−72+6−10+50

Continue the addition and subtraction: (10−72)+6−10+50=−62+6−10+50(10−72)+6−10+50=−62+6−10+50

Continue until the final result: (−62+6)−10+50=−56−10+50=−16+50=34(−62+6)−10+50=−56−10+50=−16+50=34

So, 4+6−8×9+6−10+50=344+6−8×9+6−10+50=34.
