I think it’s A I’m not sure though
When multiplying by a number that is 1 with 0's on the end, you move the decimal to the right by how many zeros there are.
Because 10,000 has 5 0's, we move the decimal 5 places to the right.
8.88 => 88800
Here we will tell you what 918 is rounded to the nearest ten and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the ten that is nearest to 918.
First, 918 rounded to the nearest ten is:
=920
Answer:
Step-by-step explanation:
The objective is to combine the terms to make one radical, so therefore we know that we will have to take a out of the second radical .
If we divide 180 by 5, we will get 36, so now we have
×
can be simplied into just 6.
So now the expression becomes
Then we can further simplify by moving the into the radical to get two common terms with .
, so we now have
So then we can combine the two radicals to get the expression to
We now see that we have two terms with a common radical, and coefficients of -1, and 48.
That allows us to simplify further to
Here, we can take out , which is , and get the final simplied form to be
Hope this helped.
