Question

If 7* 1 = 64 and 3 * 9 = 144, then the value of 5 * 6 is
(A) 22
(B) 55 (C) 66 (D) 121​

Answer 1

Answer:

5*6=(5+6)^2=11^2=121

7*1=(7+1)^2=(8)2=64

Answer 2

Answer:

Option (D ) 121 is the correct answer.

Step-by-step explanation:

Explanation:

Given , 7*1 = 64 and 3 * 9 = 144 .

We get the specified value by adding both integers and then squaring the result.

Step 1:

From the question we have ,  7*1 = 64

On adding 7 and 1 we get ,

⇒7 + 1 = 8  .

And the  square of 8 is 64 .

⇒ 7 + 1 = 8 ⇒ $8^2$ = 64

Similarly , on applying the same method we get ,

3 *  9 =  144

3 + 9 = 12 ⇒ $12 ^2$ = 144

Therefore ,   adding 5 and 6 we get

5 + 6 = 11

And the square of 11 is  121 .

Final answer:

Hence , 121 is the required value of  5* 6.
