3. Understand and calculate indices3 4
Know the meaning of base and index.
Know the value of 43
Know the value of
43 × 52.

4. A number has two parts:
In this case, we have written the number 2 to the power of 3. This is sometimes called, “two cubed.”
Two cubed means we do 2×2×2 which is 8.
Note that we do not do 2×3.

5. 42 = 4 × 4 = 52 62
24 = 2 × 2 × 2 × 2 = 33 43 72
32 × 52 = 3 × 3 × 5 × 5 =
23 × 3 × 42 = 2 × 2 × 2 × 3 × 4 × 4 =
33 × 52 × 6 =
43 × 5 =
26 × 32 =

6. The answers are next…

7. 42 = 4 × 4 = 16
52 = 5 × 5 = 25
62 = 6 × 6 = 36
24 = 2 × 2 × 2 × 2 = 16
33 = 3 × 3 × 3= 27
43 = 4 × 4 × 4= 64
72 = 7 × 7 = 49
32 × 52 = 3 × 3 × 5 × 5 = 225
23 × 3 × 42 = 2 × 2 × 2 × 3 × 4 × 4 = 384
33 × 52 × 6 = 3 × 3 × 3 × 5 × 5 = 675
43 × 5 = 4 × 4 × 4 × 5 = 320
26 × 32 = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 = 576
