Answer:
1.6 please correct me if im wrong by commenting
Step-by-step explanation:
Answer:
+
Step-by-step explanation:
We sure can write 2^2/5+ 3^1/10 as
// use the to transform the expression
Convert to = (here a = 2, n = 5, m = 2)
Then convert to = (here a = 3, n = 10, m = 1)
Now we get = + . This is the simplified form, which is the answer.
Answer:
4.5 and -1.1 are rational numbers, -6 is an integer, and 12 is a whole number.
Step-by-step explanation:
<u>Numbers:</u>
<u>Let's see which option is correct:</u>
-1.1 is a rational number, 4.5 and -6 are integers, and 12 is a whole number.
- 4.5 in not an integer, it is incorrect
-1.1 and -6 are rational numbers, 12 is an integer, and 4.5 is a whole number.
- 4.5 is not a whole number, this is incorrect
4.5 and -1.1 are rational numbers, -6 is an integer, and 12 is a whole number.
12 is a rational number, -1.1 and -6 are integers, and 4.5 is a whole number.
- -1.1 is not and integer, 4.5 is not a whole number, this is incorrect
Divide both sides by 3.1 and find g = 20.9/3.1 ≈ 6.7 ≈ 7.
You can estimate this without a calculator by saying 20.9 ≈ 21 and 3.1≈3, then 21/3=7.
In general, be careful with rounding before a calculation, because the rounding errors can be enlarged, messing up the accuracy of your answer. It's best to round only at the end.
