Question 1 )          Simplify 6 3 + 3 3     A )  3 5      B) 3 6          c)  6 3             D) 6 4 Question 2  )    Simplify  4 3 + 4 3 + 4 3 + 4 3 + 3 2 + 3 2 + 3 2   (A) 4 4 + 3 3   (B)4 2 + 3 6      (C)4 3 (3 2 )     (D) 2 6 + 3 6 Question 3)  Simplify     4 8 – 8 4                                           -----------------                                                    2 4 + 4 2 (              A)    1/2 5            (B) 2 2 (7)      (C)  2 7 (15) Explanation Question 1 )  Begin by breaking 6 down into its prime factors. 6 3 + 3 3 = (2 x 3) 3 + 3 3 = Now each term contains (33). Factor it out. (2 3 )(3 3 ) + 3 3 = 3 3 (2 3 + 1) = 3 3 (9) = 3 3 (3 2 ) = 3 5 . Explanation Question 2)     Factor 4 3 out of the first four terms and factor 3 2 out of the last three terms. 4 3 + 4 3 + 4 3 + 4 3 + 3 2 + 3 2 + 3 2 = 4 3 (1 + 1 + 1 + 1) + 3 2 (1 + 1 + 1) = 4 3 (4) + 3 2 (3) = 4 4 + 3 3

PEMDAS Overview When you simplify a maths expression, don’t automatically perform operations from left to right, even though that’s how you read English or HIndi. Instead, follow PEMDAS: Parentheses Do P first Exponents Then E Multiplication  or Division Then either M or D Addition or Subtraction Then either A or S For 3 + 2 x 4, you do the M first (multiply 2 and 4), then the A (add 3 to the result). 3 + 2 x 4 = 3 + 8 = 11 If you want to force the addition to go first, add parentheses. P always goes first: (3 + 2) x 4 =5 x 4 = 20 Multiplication and Division are at the same level of importance in PEMDAS , because any Multiplication can be expressed as a Division, and vice versa. In a sense, Multiplication and Division are two sides of the same coin. Likewise, Addition and Subtraction are at the same level of importance. Any Addition can be expressed as a Subtraction, and vice versa. If you have two operations of equal importance, do them left to right. 3 -
