Question

if 8*3=14, 13*8 =4 and 1*9 =54 then find the value of 7*3​

Answer 1

The value of 7*3 is "6".

Step-by-step explanation:

We have,

8*3 = 14, 13*8 = 4 and 1*9 = 54

The pattern follow,

$(Difference of two numbers)^{2}$ - (Addition of two numbers)

8*3 = $(8 - 3)^{2}$ - (8 + 3) = 25 - 11 = 14

13*8 = $(13 - 8)^{2}$ - (13 + 8) = 25 - 21 = 4

1*9 =  $(1 - 9)^{2}$ - (1 + 9) = 64 - 10 = 54

Similarly,

7*3= $(7 - 3)^{2}$ - (7 + 3) = 16 - 10 = 6

Hence, the value of 7*3 is "6".
