Solution

We know that for any non-zero integer a and natural numbers m and n, we have , am×an=am+n.

Also, in other words, powers will get added when base is same and powers are different.

In (-3)4×(-3)6, we have same base (-3) and different powers, so , we will add the powers.

Thus, (-3)4×(-3)6=(-3)4+6=(-3)10.

Hence, (-3)4×(-3)6 as a single exponent is (-3)10.
