Write each power of ten in standard notation. 10‐³
1 answer:
9514 1404 393
Answer:
0.001
Step-by-step explanation:
In our base-10 place-value number system, the "places" correspond to powers of 10. Those powers start at 0 in the "ones place", and increase by 1 for each place to the left. That is, the 10s place digits have a place value of 10^1, the 100s place digits have a place value of 10^2 and so on.
The place values to the right of the decimal point work the same way. For each place to the right, the exponent decreases by 1. The tenths place (0.1) digits have a place value of 10^-1, the hundredths place (0.01) digits have a place value of 10^-2, and the thousandths place (0.001) digits have a place value of 10^-3.
10^-3 = 0.001

<em>Additional comment</em>
Some places, 10^-3 <em>is</em> standard notation. That is, what is defined as "standard" varies around the world.

Answer:
<em>ab+bc+ca=0</em>
Step-by-step explanation:
We are given:
xyz=1
Separating equations:
Solving the first equation for x:
Solving the second equation for y:
Substituting in
xyz=1:
Adding the exponents:
Since :
The base is z on both sides so we get rid of them:
Multiplying by ab:
bc+ac+ab=0
Reordering:
ab+bc+ca=0
