Expand (1+0.5x)4 , simplifying the coefficients. Step 1. Draw Pascal's triangle to find the coefficients       1 ;  1  2  1 ; 1  3  3  1 ; 1  4  6   4  1. As you can see, each row starts ...

To solve Inx + In3 = In6 we must follow some basic log rules, log_b(mn) = log_b(m) + log_b(n)if we compare this with the...

This question tests a variety of mathematical techniques and knowledge which is integral to A-level mathematics.

Note that the highest power of a variable function in the mentioned equatio...

This question is a classic example of a problem which might catch some students out, if due care is not implemented.
