Question

Write 8xmxn without the multiplication sign

Answer 1

Step-by-step 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,

$\text{We write }a^2b^3c^4\text{ and mean }a^2\times b^3\times c^4$

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

$\frac ab\cdot \sqrt{\frac{d^4}{b^9}}\cdot\pi$
