Answer:
(6x6x6x6)x(6x6)
Explanation:
6 to the power of 4 times 6 to the power of 2
If a number a is to the power of b, that means a multiplied by itself, b times
eg 4 to the power of 3 means 4x4x4
hence, 6 to the power of 4 (or superscript four) means 6 itself, 4 times
so, 6x6x6x6 multiplied by 6x6
