Question Detail
\begin{aligned} (1000)^7 \div (10)^{18} = ? \end{aligned}
- 10
- 100
- 1000
- 10000
Answer: Option C
Explanation:
\begin{aligned}
= \frac{(10^3)^7}{(10)^{18}}
\end{aligned}
\begin{aligned}
= \frac{(10)^{21}}{(10)^{18}} = 10^3 = 1000
\end{aligned}
1. \begin{aligned}
\text{if }6^m = 46656, \\\text{ What is the value of }6^{m-2}
\end{aligned}
- 7776
- 7782
- 1296
- 1290
Answer: Option C
Explanation:
\begin{aligned}
6^{m-2}\\ = \dfrac{6^m}{6^2}\\ = \dfrac{46656}{6^2}\\ = \dfrac{46656}{36} = 1296
\end{aligned}
2. Value of \begin{aligned} (256)^{\frac{5}{4}} \end{aligned}
- 1012
- 1024
- 1048
- 525
Answer: Option B
Explanation:
\begin{aligned}
= (256)^{\frac{5}{4}} = (4^4)^{\frac{5}{4}} = 4^5 = 1024
\end{aligned}
3. \begin{aligned} \sqrt{8}^\frac{1}{3} \end{aligned}
- 2
- 4
- \begin{aligned} \sqrt{2} \end{aligned}
- 8
Answer: Option C
Explanation:
\begin{aligned}
= ((8)^\frac{1}{2})^\frac{1}{3} = 8^{(\frac{1}{2} \times \frac{1}{3})}
\end{aligned}
\begin{aligned}
= (8)^{\frac{1}{6}}
\end{aligned}
\begin{aligned}
= (2)^{3(\frac{1}{6})}
\end{aligned}
\begin{aligned}
= (2)^{\frac{1}{2}}
\end{aligned}
4. Find the value of
\begin{aligned} (10)^{150} \div (10)^{146} \end{aligned}
- 10
- 100
- 1000
- 10000
Answer: Option D
Explanation:
\begin{aligned}
= \frac{(10)^{150}}{(10)^{146}} = 10^4 = 10000
\end{aligned}
5. \begin{align}
\left(\dfrac{a}{b}\right)^{x-2} = \left(\dfrac{b}{a}\right)^{x-7}.\\\text{ What is the value of x ?}
\end{align}
- 1.5
- 4.5
- 7.5
- 9.5
Answer: Option B
Explanation:
\begin{align}&\left(\dfrac{a}{b}\right)^{x-2} = \left(\dfrac{b}{a}\right)^{x-7}\\\\
&\Rightarrow \left(\dfrac{a}{b}\right)^{x-2} = \left(\dfrac{a}{b}\right)^{-(x-7)}\\\\
&\Rightarrow x - 2 = -(x - 7)\\\\
&\Rightarrow x - 2 = -x + 7\\\\
&\Rightarrow x-2 = -x + 7\\\\
&\Rightarrow 2x = 9\\\\
&\Rightarrow x = \dfrac{9}{2} = 4.5
\end{align}
