2+2+5= 9answer

Answer 2

Answer:

$\large\boxed{\sf{15\times15=9}}$

Step-by-step explanation:

Given that a series, having hidden codes, such that,

• 12 × 12 = 9
• 14 × 14 = 16

To find the value of,

• 15 × 15 = ??

Lets head to the first expression.

12 × 12 = 9

We know that, 12 × 12 = 144

Now, add the numbers in 144.

Therefore, we will get,

= 1 + 4 + 4

= 9

That's the desired result given.

Now, let's see the second expression.

14 × 14 = 16

But, we know that, 14 × 14 = 196

Now, add the digits of 196.

Therefore, we will get,

= 1 + 9 + 6

= 16

That's the desired result given.

So, for the expression 15 × 15 .

We know that, 15 × 15 = 225

Now, adding the digits of 225.

Therefore, we will get,

= 2 + 2 + 5

= 9

Hence, the required value of 15 × 15 = 9
