Question

standard form and contain only positive exponents 21c^10d^3+56c^6d^2-7c^2d------------------------------------------- 7c^2d

Answer 1

To solve this problem it is necessary to simplify the expression.

Step 1. Write the equation as a sum of homogeneous fractions:

`(21c^(10)d^3+56c^6d^2-7c^2d)/(7c^2d)=(21c^(10)d^3)/(7c^2d)+(56c^6d^2)/(7c^2d)-(7c^2d)/(7c^2d)`

Step 2. Simplify the obtained expressions:

`\begin{gathered} (21c^(10)d^3)/(7c^2d)=3c^8d^2 \\ (56c^6d^2)/(7c^2d)=8c^4d \\ (7c^2d)/(7c^2d)=1 \end{gathered}`

Step 3. Rewrite the expression using the simplified terms:

`3c^8d^2+8c^4d-1`
