QUESTION 1 [6 marks]
Powers and Roots:
a) Simplify 75 x 72 (2 marks)
using the indices rule, we add the power when there is multiplication
= 75 +2=77
= 823543
b) Simplify 103 ÷102 (2 marks)
when there is division, we subtract the powers using the rule of indices.
= 103−2=101 = 10
c) Evaluate ( 123 )4 (2 marks)
In this case, the powers are multiplied as they are within a bracket.
= 123 ×4 =1212 = 8916100448256

√ 23 −4 3
√ 23
= 7 ×2−4 × 2 = 14 – 8
= 6
d) Scientific notation allows one to express large or small numbers in a simpler form.
