Question

Calcule os valores das expressões:
a)(1,2)3+1,3
b)20-(3,6)2
c)(0,2)2+(0,8)2
d)(1,5(2-(0,3)2
e)1-(0,9)2
f)100x(0,1)5
g)4/2÷0,5-(1,5)2
h)(1-0,7)+(7-6)5

Answer 1

a)(1,2)³+1,3  =1,728+1,3 =3,028

b)20-(3,6)²= 20-12,96=7,04

c)(0,2)²+(0,8)2² =0,04 +0,64=0,68

d)(1,5)²-(0,3)² =2,25-0,09=2,16

e)1-(0,9)² = 1-0,81=0,19

f)100x(0,1)^5 =100 x 0,00001=0,001

g)4/2÷0,5-(1,5)²= 4/2:5/10-2,25⇒ 4/2 x10/5  -2,25=4-2,25=1,75

h)(1-0,7)+(7-6)^5=0,3+1=1,3
