Multiply 3.4 x 10\(^{-5}\) by 7.1 x 10\(^8\) and leave the answer in standard form. 

Given that P = {p: 1< p < 20}, where p is an integer and R = {r : 0 \(\leq\) r \(\leq\) 25, where r is a multiple of 4}. Find P ∩ R

The first term of an Arithmetic Progression (A.P) is 2 and the last term is 29. If the common difference is 3, how many terms are in the A.P.?

Express in index form: log\(_a^x\) + log\(_a^y\) = 3 

Simplify: (2p - q)\(^2\) - (p + q)\(^2\)
