Question

Simplify 3^4 x 3^6 x 3^-6, leaving your answer in the form a^n where 'a' is a whole number.

Answer 1

3^4 * 3^6 * 3^-6= 81. There is no exponent. It is just a whole number.

or it can be written

81 * 729 * 1/729 = 81

Answer 2

`{3}^(4) * {3}^(6) * {3}^( - 6) \\ = {3}^(4 + 6 + ( - 6)) \\ = {3}^(4 + 6 - 6) \\ = {3}^(4)`
The answer is 3^4
