It becomes 5 if you round it to the nearest tenth
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>
Suppose the one's digit is x, the ten's digit is y. the original number is 10y+x, the reversed number is 10x+y
x+y=13
(10x+y)=(10y+x)-9 =>9y-9x=9 =>y-x=1
Add the two equation to solve: 2y=14 =>y=7
x=13-7=6
the original number is 76.
Answer: 18 OB. 8 x + -10 oc. 11 x + 12.45 8 OD= 8
