Question

How do you multiply `(3k ^ { 4} d ^ { 6} ) ( 6d ^ { 3} j ^ { 4} )`?

Answer 1

Using indices first law, you can multiply the two d units together. `3k^4*6d^(6+3)*j^4` and thus the final answer would be `18k^4d^9j^4`

Explanation:

The trick is to put the d units together. `6d^3*d^6` would equal to `6*d^(3+6)=6d^9`

Grouping using brackets where appropriate to highlight the relationships.

`(3xx6)(k^4)(d^6d^3)(j^4)`

`18k^4d^9j^4`
