Simplifying exponents

4^5 . 4^6 4^__ B. M^10 . M^100 __^_

Using the property of exponents, when multiplying two exponents with the same base, you add their exponents:

4^5 * 4^6 = 4^(5+6) = 4^11

Similarly,

M^10 * M^100 = M^(10+100) = M^110

Therefore, the simplified expressions are:

4^5 * 4^6 = 4^11

M^10 * M^100 = M^110
