1 answer:
Hey ,
Here is the answer to ur question...
Given: A triangle in which area =144root3 cm^2....
To find: Perimeter of the triangle...
Solution: As we know area of an equilateral triangle =root3/4 a^2.....
and given area is 144root3
=>Area =144root3
=>root3/4a^2=144root3
=>a^2=144root3*4/root3
=>a^2=144*4
=>a^2=576
=>a=root576
=>a=24
So,now we got each side of the triangle as 24cm.
=>perimeter=side*3=24*3=72cm....
Hope this helps u....

To convert a fraction to simplest form we need to find the greatest common factor.
The fraction can not be simplified because it is already in simplest form but we can change it to a mixed fraction.

Given expression .
Let us simplify step by step with explaination.
Let us read the given expression.
could be read as a power 3 and whole power 2.
Because we have whole power 2 of a^3. That represents two factors of (a^3) is there. So, we could write two factors of a^3 as (a^3)(a^3).
So, first step is (a^3) (a^3).
Now, each of the factor has a^3.
That is read as a power 3, that is three factors of a.
So, we can write a^3 in expanded form as a*a*a.
For each a^3, we would write a*a*a.
We have two facrors of a^3 there.
So, (a^3)(a^3) could be written as (a*a*a)(a*a*a).
There are 3+3=6 factors of a's there.
So, we could rewrite (a*a*a)(a*a*a) as 6 power of a.
That is a^6.
Therefore, we got the steps :
(a^3)^2 = (a^3)(a^3) = (a*a*a)(a*a*a) = a^6.
