What is the sum of 7 * 10 - the power of 8 and 10 * 6 - the power of 8 is it 13 * 10 ^ 8 1.3 * 10 - the power of 7 13 * 10 - 16
The expression 7 * 10 - the power of 8 is equal to 7 * 10^8.
Similarly, the expression 10 * 6 - the power of 8 is equal to 10 * 6^8.
Therefore, the sum of these two expressions is:
7 * 10^8 + 10 * 6^8 = 13 * 10^8.
So the correct answer is 13 * 10^8, which is equivalent to 1.3 * 10^9.
