Question 1

1.

Draggable item		Corresponding Item

Use
1) The definition of exponentaiton:
a^{b}=a\cdot a\cdot a \cdot ... \cdot a, b times
2) The commutativity of multiplication
ab=ba
3) the associativity of multiplication
abc=a(bc)=(ab)c
To Prove
(ab)^{n}=a^{n}b^{n}

Question 3

3.

Use
1) The definition of exponentaiton:
a^{b}=a\cdot a\cdot a \cdot ... \cdot a, b times)
2) The rule for multiplying fractions:
\frac{a}{b}\cdot\frac{c}{d}=\frac{ac}{bd}
To Prove
(\frac{a}{b})^{n}=\frac{a^n}{b^n}

Question 4

4.

Which of the following rules are true?

(a^{m})^{n}=a^{m \cdot n}

(a^{m})^{n}=a^{m+n}

a^{m} \cdot a^{n}=a^{m \cdot n}

a^{m} \cdot a^{n}=a^{m + n}
