To simplify the expression (3i)(7i), we can use the property of multiplication of complex numbers which states that i^2 is equal to -1.
Therefore, we have:
(3i)(7i)
= 3 * 7 * i * i
= 21 * i^2
= 21 * (-1)
= -21
So, the simplified expression is -21.
Therefore, we have:
(3i)(7i)
= 3 * 7 * i * i
= 21 * i^2
= 21 * (-1)
= -21
So, the simplified expression is -21.
