4^5*7^10 RAISED TO SINGLE POWER

Explanation:

The rule used is

a^b*a^c = a^(b+c)

Basically you add the exponents. This only applies if the bases are both the same. In this case, they're both 4 so the rule works out.

Using the rule, we get

a^b*a^c = a^(b+c)

4^5*4^10 = 4^(5+10)

4^5*4^10 = 4^15

because 1.2 isnt half of 6 duh
