Explanation
This is a problem requiring you to do a factorial of the number 6. This is done by taking the number and multiplying it by the next smallest number times the next smallest, all the way down to 1, or: 6 * 5 *4 * 3 * 2 * 1 = 720.
\(\sqrt {{{(6 + x)}^2}} = \)
\( (x - 5)({x^2} + 7x + 2) = ? \)
\(2(5+3 \times \sqrt{25}) \div(14-9) \times 4=?\)
\( {({6^3})^9}? \)
