Answer 2

The required option (C) 9* 8 = "217".

Step-by-step explanation:

We have,

3*7 = 79, 8*4 = 112 and 7*6 = 127

To find 9* 8 =?

The patter is,

$(Sum of two numbers)^{2}$ - Product of numbers

3*7 = $(3 + 7)^{2}$ - 3 × 7 = 100 - 21 = 79

8*4 =  $(8 + 4)^{2}$ - 8 × 4 = 144 - 32 = 112

7*6 =  $(7 + 6)^{2}$ - 7 × 6 = 169 - 22 = 127

Similarly,

9* 8 =  $(9 + 8)^{2}$ - 9 × 8 = 289 - 72 = 217

Hence, the required option (C) 9* 8 = 217.
