1.1. The table below shows corresponding values of $x$ and $y$ for $y={log}_{3}2x$

The values of $y$ are given to 2 decimal places as appropriate.

Using the trapezium rule with all the values of $y$ in the table, find an estimate for

${\int}_{3}^{9}{log}_{3}2xdx$

1.2. Using your answer to part (a) and making your method clear, estimate

(i) ${\int}_{3}^{9}{log}_{3}{(2x)}^{10}dx$

(ii) ${\int}_{3}^{9}{log}_{3}18xdx$
