Question

7z2 5z4 d3 d8
I don't know how you are supposed to do it?

Answer 1

`35 {z}^(6) {d}^(11)`

Explanation:

Assuming you are supposed to simplify:

`7 {z}^(2) * 5 {z}^(4) * {d}^(3) * {d}^(8)`

Then we need to apply the product rule of indices.

`{a}^(m) * {a}^(n) = {a}^(m + n)`

So we multiply to get:

`35 {z}^(2 + 4) * {d}^(3 + 8)`

We now simplify the exponents to get:

`35 {z}^(6) * {d}^(11)`

Therefore the required product is

`35 {z}^(6) {d}^(11)`
