no idea sorry

Step-by-step explanation:

good night

Answer 2

Answer:

Basically if I have something like 2² * 3², they're just telling me to write like (number)^(number) i.e a single number raised to an exponent.

So, in my example we know a^m * b^m = (ab)^m, hence 2² * 3² = (2*3)² = 6²; i.e we use the laws of exponents to simplify to get this form.

Now, the solutions to your questions will become,

(a) (xy)³

(b) (xy)ᵃ

(c) (12)ᵃ

(a),(b),(c) all use a^m * b^m = (ab)^m.

(d) This needs one more thing. We can't simply combine them directly.

First we should write 4=2² and 8=2³.

We also know, (a^m)^n = a^mn.

So, 4ᵃ = 2²ᵃ and 8² = 2⁶.

Therefore, we simplify to get 2²ᵃ⁺⁶as the answer.
