Question

calculati x, x la puterea a 2-a si x la puterea a 3-a in fiecare dintre cazurile:

a) x = 17,3 - 8,9
e) x = 5 - 3,98

Va rog..

Answer 1

x=17,3-8,9=>x=8,4
x²=8,4²=7.0,56
x³=8,4³=592,704
x=5-3,98=>x=1,02
x²=1,02²=1,0404
x³=1,02³=1,061208

Answer 2

a) x=8,4
x²=70,56
x³=592,704
e)x=1,02
x²=1,0404
x³=1,061208
