Find the value of \( (2^{1/4} - 1) (2^{3/4} + 2^{1/2} + 2^{1/4} + 1) \)
If the sales tax reduced from \( 3 \frac{1}{2} \% \) to \( 3 \frac{1}{3} \% \), then what difference does it make to a person who purchases an article with market price of Rs. 9000?
A man owns \(\frac{2}{3}\) of the market research bureau business and sells \(\frac{3}{4}\) of his shares for Rs. 75000. What is the value of the business?
Solve: ( x + y = x2 - y2 = 23 ), find ( y ).
Simplify: \( \log \frac{75}{16} - 2 \log \frac{5}{9} + \log \frac{32}{243} \)
