**Reading Exponents**

**Examples on evaluating powers (exponents):**

**1. Evaluate each expression:****(i) **5^{4}.

**Solution:**

5^{4}

= 5 ∙ 5 ∙ 5 ∙ 5 → Use 5 as a factor 4 times.

= 625 → Multiply.

**(ii) **(-3)^{3}.

**Solution:**

(-3)^{3}

= (-3) ∙ (-3) ∙ (-3) **→ Use -3 as a factor 3 times**.

= -27 → **Multiply**.

**(iii) **-7^{2}.

**Solution:**

-7^{2}

= -(7^{2})

= -(7 ∙ 7)

= -(49)

= -49
