(axb)m=ambm Lesson 6
How does it work? • This is the same as the previous rule, because one index number is inside brackets and the other is outside the indices are multiplied together. (axb)m =(a1 xb1)m = a1xmxb1xm = ambm
Example (axb)m=ambm (7xb)9 =79b9 • This all the working which is required for this task. Remember that both numbers need to be multiplied.
