2x2 or ‘2 lots of x squared’ means 2 × x × x and (2x)2 or ‘2x all squared’ means 2x × 2x = 4x2. 2 In questions 1 to 24, write the expressions in their simplest forms. 1 4a × 3 2 5x × 2y 4 7m × 3n 7 3a × 4b × 5c 9 x2 × x 10 a × a2 × a 11 x2 × x2 12 a3 × a3 13 2a2 × a3 14 3x3 × 2x4 15 2ab × ab 16 2b × 3b8 17 x2y × xy2 18 7x3 × x3a 19 2a × 3a2 × a3x 20 (3a2b)3 21 (x3)2 22 (2a4)3 23 (2a3)4 24 (4a)2 × 4a2 In questions 25 to 32, find the numerical values of the given expressions. 14 Division of powers Suppose that a power of a number is divided by another power of the same number, as for example, Every division can be expressed in fractional form, as in arithmetic.

So starting from (−2), you move 5 divisions to the left and read (−7). 2. 1 1 A lift starting from the ground floor rises to the fourth floor. Then it descends to the second floor, rises to the sixth floor and finally descends to the ground floor. Express its movements by using positive and negative numbers. 2 The movement of the mercury in a thermometer was as follows.

Multiplication may also be shown by a dot, so 2 · n means 2 × n or 2n. If any odd number can be represented by 2n + 1, then, since when any odd or even number is increased by 2 the result is the next odd or even number, the next odd number greater than 2n + 1 is 2n + 1 + 2 or 2n + 3. Similarly 2n + 5 is the next odd number above 2n + 3. So the expressions form a sequence, or a succession of consecutive increasing odd numbers. Similarly, if you subtract 1 from an even number, you obtain an odd number.
