Answer:
the GPE is 1/2 the unit of measure used to make the measurement or you say 1/2 the most precise unit
12.3 L has 0.1 as the most precise unit of measure, so 1/2 of 0.1 is 0.05 L which is c. above
look at it this way: 12.3 can be any number between 12.25 and 12.34 rounded to the nearest tenth
any number from 12.25 to 12.34 rounded to the nearest tenth gives you 12.3, so the GPE that you can possibly make is 0.05; if the number was 12.24 it would round down to 12.2 not up to 12.3 and if the number was 12.35 it would round up to 12.4 not round down to 12.3, so again the greatest possible error that you can make is 0.05
Answer:
x=500
Step-by-step explanation:
To solve the equation given, we will follow the steps below:
log 20x³ - 2log x=4
using the law of logarithm,
2log x = log x²
so, our equation becomes;
log 20x³ - log x²=4
Also using another law of logarithm;
log 20x³ - log x² = log (20x³/x²)
our equation becomes;
log (20x³/x²) = 4
log 20x = 4
from the definition of logarithm, logarithm is the power of the exponential
10⁴ = 20 x
10000 = 20x
divide both-side of the equation by 20
10000/20 = 20x/20
at the right-hand side of the equation 20 will cancel-out 20 leaving us with just x and the left-hand side of the equation, 10000 will be divided by 20
500 = x
x = 500
Answer:
If you want a deteled answer tell me!
Step-by-step explanation:
Since 
, the idea here is to find 
such that
Expanding the left side completely, we find two possibilities:
so that can be either positive or negative 20.
