Question

2+16=08
4+36=24
8+49=56
9+64=??

Answer 1

Answer:

$\boxed{9+64 = 72}$

Step-by-step explanation:

$\large\mathtt{2+16=08}$..........(1)

$\large\mathtt{4+36=24}$..........(2)

$\large\mathtt{8+49=56}$...........(3)

$\large\mathtt{9+64=?}$............(4)

In case 1,

• We have 2 + 16 = 08.
• The square of the second digit 16 is 4. Means, 4 × 4 = 16.
• Now, we got 2 + (4)² = 08.
• Just multiply 4 with 2, you will get 08.
• It means, 2 × 4 = 8.
• So, we got our answer here!

In case 2,

• We have 4 + 36 = 24.
• Again, the square of the second digit 36 is 6.
• Now, we got 4 + (6)² = 24.
• Multiply the first digit 4 with 6, you will get 24.
• 4 × 6 = 24.
• We got our answer here too!

In case 3,

• We have 8 + 49 = 56.
• The square of 49 is 7.
• We got 8 + (7)² = 56.
• Multiply 7 with 8. You will get 56.
• 7 × 8 = 56.
• We got our answer here too.

In case 4,

• We have 9 + 64 = ?.
• The square of 64 is 8.
• We got 9 + (8)² = ?.
• Multiply 8 with 9. You will get 72.
• 8 × 9 = 72.
• So, hence our answer is 9 + 64 = 72.

Answer 2

Answer:

• 2 + 16 = 08

Here, simplifying it.

= 2 + (4)²

Multiplying the numbers.

= 4 × 2 = 8.

• 4 + 36 = 24

Here, simplifying it.

= 4 + (6)²

Multiplying the numbers.

= 6 × 4 = 24.

• 8+49=56

Here, simplifying it.

= 8 + (7)²

Multiplying the numbers.

= 8 × 7 = 56.

• At last, 9+64=??

Here, similarly, 9 + (8)²

= 9 × 8

= 72.

------------------------

Steps used:-

• The second number is to be simplified.
• The number obtained in the simplification should be multiplied.
• No other mathematical operation is to be done.
• The resultant number is the final answer.
