Given that a*b = a + b + ab
a) evaluate 3*5
just plug and chug
3*5 = 3 + 5 + 15 = 23
Find the inverse of the matrix A=(5/-3 7/-2)
3+3×5=6×5=30
To evaluate the expression 3*5 using the given equation a*b = a + b + ab, we can substitute a with 3 and b with 5.
So, a = 3 and b = 5. Plugging these values into the equation, we have:
3*5 = 3 + 5 + 3 * 5
Now, we can simplify the expression:
3*5 = 3 + 5 + 15
Adding the numbers together:
3*5 = 8 + 15
3*5 = 23
Therefore, the value of 3*5 is 23.
