Question

3*7=79,8*4=112,7*6=127,then find the value of 9*8​

Answer 1

The value of 9*8 is "217".

Step-by-step explanation:

We have,

3*7 = 79, 8*4 = 112, 7*6 = 127 and 9*8 = ?

The pattern is $(Sum of two numbers)^{2}$ - (Product of two numbers).

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

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

7*6 = $(7 + 6)^{2}$ - (7 × 6) = 169 - 42 = 127,

Similarly,

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

Hence, the value of 9*8 is "217".
