20 cubed cubed = [203]3 = (20 x 20 x 20)3 This equals 20 x 20 x 20 x 20 x 20 x 20 x 20 x 20 x 20 which = (20)9 The rule to work it out is:multiply the two exponents ie 3 x 3 = 9 206 is 20 x 20 x 20 x 20 x 20 x 20 which is obviously less than 209.

20% of 67 is (67/100) x 20 = 0.67 x 20 and we have to add the original 20 to this, so the total is 20 + (0.67 x 20) = 20 x 1.67 = 2 x 16.7 = 33.4

204 = 20 x 20 x 20 x 20 = 160000
The first ten integer multiples of 20 are: 1 x 20 = 20 2 x 20 = 40 3 x 20 = 60 4 x 20 = 80 5 x 20 = 100 6 x 20 = 120 7 x 20 = 140 8 x 20 = 160 9 x 20 = 180 10 x 20 = 200
x = 77 x + 20 = 97 x = 97 - 20 x = 77
x % of 80 = 20 = x / 100 x 80 = 20 = 8 x / 10 = 20 = x = 20 x 10 / 8 = x = 25% (answer)
