Simplify the following
`(5i) xx 7`

Answer

To simplify the expression \( (5i) \times 7 \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the components**: We have \( 5i \) (where \( i \) is the imaginary unit) and \( 7 \) (a real number).

2. **Multiply the real number with the imaginary number**:
\[ (5i) \times 7 = 5 \times 7 \times i \]

3. **Calculate the multiplication**:
\[ 5 \times 7 = 35 \]

4. **Combine the results**:
\[ 35i \]

Thus, the simplified form of \( (5i) \times 7 \) is:
\[ \boxed{35i} \]
