√-80 can be factored out, to see which factors can be square rooted. A pair of factors would be 16 and -5, so that would be 4√-5. But, negative numbers cannot be inside a square root. So, √-1 is the same thing as <em>i</em>, or <u>imaginary number</u>. So, the expression equivalent to √-80 is 4<em>i</em>√5.

The question given here has two parts and each part has to be answered separately. In case of both the multiplications, the answer might look to be huge but by applying a simple technique, anybody can do these multiplications without the help of any calculator.
Now let us take the case of first multiplication that is given:
50000 * 700
= 35000000
In this case all the zeroes present has to be written first and then 7 and 5 should be multiplied and put. This will get the answer easily.
Now we take the second multiplication given:
100 * 123478
= 12347800
In this case also the zeroes are simply put on the right side of the number 123478.
Answer:
The angles from largest to smallest are:
∠A
∠B
∠C
Step-by-step explanation:
We can see in the diagram that
AB = 7
AC = 8
BC = 9
The angles opposite to sides are as follows:
∠A is opposite to BC
∠B is opposite to AC
∠C is opposite to AB
The angle opposite to the largest side of the triangle is the largest and the angle opposite to smallest side of the triangle is the smallest in measurement
Arranging the sides from largest to smallest:
BC, AC, AB
Similarly the angles opposite them will be arranged according to them
∠A, ∠B, ∠C
Hence,
The angles from largest to smallest are:
∠A
∠B
∠C
The height is around 4.77 mm
To write 32,005,008 in expanded form, you write it out like this: <span>32,005,008 = 30,000,000 + 2,000,000 + 5,000 + 8.
I know this because I learned it in 3rd grade at school.
Hope I helped!
