If you're going to write negative exponents, please enclose them inside parentheses:
12 / c^(-8)
12 8d^2
<span>12/c^-8d^2 becomes --------- - ---------
c^8 1
Here the LCD is c^8, so the above expression becomes:
12 c^8*d^2 12-(c^8)(d^2)
------- - ------------- = ---------------------
c^8 c^8 c^8</span>
Answer:
22 and 46
Step-by-step explanation:
let
one number is x
another is 2x+2

or, 3x+2=68
3x=66
or x=66/3=22
so one number is 22 and another is (22X2+2)=46
