Question

Write 8xmxn without the multiplication sign

Answer 1

Explanation:

`8mn`

or equivalently

`8\cdot m\cdot n`

We often write variable side-byside without the multiplication sign in algebra. It also applies to terms with indices. For instance,

`\text{We write }a^2b^3c^4\text{ and mean }a^2* b^3* c^4`

We may, often also add a dot at the middle of both terms as another version of multiplication sign for better readability if the terms are more complicated, for instance

`a\cdot b\cdot c`

and

`\frac ab\cdot \sqrt{(d^4)/(b^9)}\cdot\pi`
