Step-by-step explanation:
Step-by-step explanation:
1/a + 1/b + 1/c = 1/(a+b+c)
=> 1/a + 1/b = 1/(a+b+c) -1/c
=> (b+a)/ab = {c - (a+b+c)/c(a+b+c)
=> (a+b)/ab = -(a+b)/(ac+bc+c^2)
=> 1/ab = -1/(ac+bc+c^2)
=> -ab = ac+bc+c^2
=-c^2 = ab+bc+ca
Similarly we can show that
-b^2 =ab+bc+ca and -c^2 = ab+bc+ca
So a=b=c. since -a^2 = -b^2 = - c^2
Then 1/a + 1/b + 1/c = 1/(a+b+c) => 3/a= 1/3a
=> 1/a^5 + 1/b^5 + 1/c^5 =3/a^5=(( 3/a )(1/a^4)
= 1/3a × 1/a^4 = 1/3a^5 = 1/(a^5 +b^5+c^^5)
Hope it help
u multiply each number with the number diagonal to it!
the area is half of the products of the numbers which were multiplied to the numbers SE to them minus the products of numbers which were multiplied to numbers southwest to them
The amount of interest after 3 years will be $15.
The complete question is given below.
You loaned a friend $100 and will charge him 5% annual simple interest when he pay it back. What is the amount of interest after 3 years?
<h3>What is simple interest?</h3>
Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
The interest is given as
I = (P × R × T) / 100
Where, P is the initial amount, R is simple interest rate, and T is the time.
We have
P = $100
R = 5%
T = 3 years
Then the interest will be
I = (100 × 5 × 3) / 100
I = $15
