Answer 1

a)
x = 8,4
$x^{2} = (8,4)^2 = 8,4 * 8,4 = 70,56$
$x^{3} = (8,4)^2 * 8,4 = 70,56 * 8,4 = 592,704$

b)
x = 14,4 - 8,4 = 6
$x^{2} = (6)^2 = 6 * 6 = 36$
$x^{3} = (6)^2 * 6 = 36 * 6 = 216$

c)
x = 2,32
$x^{2} = (2,32)^2 = 2,32 * 2,32 = 5,3824$
$x^{3} = (2,32)^2 * 2,32 = 5,3824 * 2,32 = 12,487168$

d)
c = 3,01
$x^{2} = (3,01)^2 = 3,01 * 3,01 = 9,0601$
$x^{3} = (3,01)^2 * 3,01 = 9,0601 * 3,01 = 27,270901$

e)
x = 1,02
$x^{2} = (1,02)^2 = 1,02 * 1,02 = 1,0404$
$x^{3} = (1,02)^2 * 1,02 = 1,0404 * 1,02 = 1,061208$

f)
x = 0,34 + 1,66 - 0,9 = 2 - 0,9 = 1,1
$x^{2} = (1,1)^2 = 1,1* 1,1 = 1,21$
$x^{3} = (1,1)^2 * 1,1 = 1,21 * 1,1 = 1,331$

g)
x = 1,4
$x^{2} = (1,4)^2 = 1,4 * 1,4 = 1,96$
$x^{3} = (1,4)^2 * 1,4 = 1,96 * 1,4 = 2,744$

h)
x = 4,944 + 0,81 = 5,754
$x^{2} = (5,754)^2 =5,754*5,754= 33,108516$
$x^{3} = (5,754)^2 * 5,754=33,108516* 5,754=190,50640106$
