Answer:
7.2224
Step-by-step explanation:
The value of the summation is given by the formula ...
Sn = (a1)(1 -r^n)/(1 -r) . . . . . where a1 is the first of n terms, and r is the common ratio.
Your sum has first term and ratio ...
a1 = 2(0.6) . . . . . summation term for n=1
r = 0.6
So the sum is ...
Then the value of the entire given expression is ...
_____
A calculator can help you find the value.
Now multiple the coefficients and add the exponents with common bases
Now write your final expression
