There's a little trick to multiplying exponents with the same number.
Basically, you are adding the exponents together, but not the whole number.
Likewise, you'll be subtracting exponents if you were to be dividing exponents.
For example;
5^3 • 5^2 = 5^5
5^5 / 5^3 = 5^2
Let's try with our numbers.
7^6 • 7^5.
Remember, we add our exponents when multiplying by the same number.
7^6 + 7^5 = 7^11.
7^11 is your product, but if you need it simplified, your answer is 1,294,139.
I hope this helps!
