By adding 104+34 and then 228+877, Then adding both of the results and finally subtracting the answer by one of the factors.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Explanation:
Which will be...
104+34=138
228+877=1,105
Then add them...
138+1,105=1,243
Finally, subtract your answer by one of the factors...
1,243-1,105
Which will result as 138. Which is also one of the factors you added earlier, that's basically what your looking fro when checking and subtraction and/or addition problem.
For every zero you move one decimal place to the left. there are 3 zeroes in 1000.
153.06
3 decimal places to the left
0.15306
Answer:
A. √500
Step-by-step explanation:
Since 500 = 5·100 = 5·10² you can move the 10² out of the √ as 10.
Hence 10√5 = √500
So we're using these rules:
√a·b = √a·√b
and of course
√a² = a (a>0)
