Answer:
Step-by-step explanation:
common ratio=18/-3=-108/18=-6, a=-3
sn=a(r^n-1)(r-1)
sn=-3((-6)^n-1)(-6-1)
sn=-3(-6)^8-1)/(-7)
s8=-3(1679615)/(-7)
s8=719836
V = a²h/3
Plugging values in we get 8.67X10^7, or 86,700,000
The simplified form of the expression; (3/4)-¹ as given in the task content is; 4/3.
<h3>What is the simplified form of the expression as given in the task content?</h3>
It follows from the task content that the expression in discuss can be simplified as follows by the laws of indices;
(3/4)-¹
Hence, due to negative exponent, the result is;
= 1 ÷ (3/4)¹
= 1 × (4/3)
= 4/3.
