Question

Is the answer to number 10 correct? if i have C^0 would i just add 1 to my answer?

Answer 1

You wouldn't add 1, but multiply. First multiply all factors with the same base. When you do that, their exponents get added:

`C^0D^(-5)D^6C^1C^2C^3=C^(0+1+2+3)D^(-5+6)=C^6D^1`

Notice how
`C^0C^1=C^(0+1)=C^1`. The factor with zero exponent contributes nothing new to the product, so the effect is the same as multiply
`C^1` by 1. In general,
`a^0=0` for any non-zero number
`a`.
