If Sn=2^n-1<br><br>what's the expression of<br>Sn-1?

Naya [18.7K]

Answer:

$S(n-1)=2^{n-2}$

Step-by-step explanation:

Given that,

The value of $S_n=2^{n-1}$

We need to find an expression for $S(n-1)$ . To find it, put the value of n as (n-1). So,

$S_{n-1}=2^{n-1-1}\\\\=2^{n-2}$

Hence, the value of S(n-1) is equal to $2^{n-2}$ .

1)

$\bf \textit{surface area of a cube}\\\\
s=6x^2\quad 
\begin{cases}
x=\textit{length of a side}\\
---------\\
s=150
\end{cases}\implies 150=6x^2\implies \cfrac{150}{6}=x^2
\\\\\\
25=x^2\implies \sqrt{25}=x\implies \boxed{5=x}$

3)

$\bf \textit{volume of a square pyramid}\\\\
V=\cfrac{b^2h}{3}\quad 
\begin{cases}
b=\textit{base's side}\\
h=height\\
-------\\
h=3\\
V=25
\end{cases}\implies 25=\cfrac{b^2\cdot 3}{3}\implies 25=b^2\cdot \cfrac{3}{3}
\\\\\\
25=b^2\cdot 1\implies 25=b^2\implies \sqrt{25}=b\implies \boxed{5=b}$
