Answer:
[tex]35 {z}^{6} {d}^{11} [/tex]
Step-by-step explanation:
Assuming you are supposed to simplify:
[tex]7 {z}^{2} \times 5 {z}^{4} \times {d}^{3} \times {d}^{8} [/tex]
Then we need to apply the product rule of indices.
[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]
So we multiply to get:
[tex]35 {z}^{2 + 4} \times {d}^{3 + 8} [/tex]
We now simplify the exponents to get:
[tex]35 {z}^{6} \times {d}^{11} [/tex]
Therefore the required product is
[tex]35 {z}^{6} {d}^{11} [/tex]
