Answer:
Step-by-step explanation:
Sum of two monomials is not necessarily always a monomial.
For example:
Suppose we have two monomials as 2x and 5x.
Adding 2x+5x , we get 7x.
So if two monomials are both like terms then their sum will be a monomial.
Suppose we have two monomials as 3y and 4x
Now these are both monomials but unlike, so we cannot add them together and sum would be 3y + 4x , which is a binomial.
So if we have like terms then the sum is monomial but if we have unlike terms sum is binomial.
Product of monomials:
suppose we have 2x and 5y,
Product : 2x*5y = 10xy ( which is a monomial)
So yes product of two monomials is always a monomial.
Answer:
<u>Volume=2.2*10^10 km^3
</u>
Step-by-step explanation:
Given
Diameter of moon=d=3476 km
The formula for the volume of sphere is:
V=4/3 πr^3
As it can be clearly seen that the formula uses radius, and we are given diameter. So we have to find the radius first
So,
radius=r=d/2
=3476/2
=1738 km
Now putting the value of r and pi in the formula:
V=4/3*3.14*(1738)^3
=12.56/3* 5249879272
= 21979494552.106
Rounded off to two significant digits:
<u>Volume=2.2*10^10 km^3
</u>
