Question

se x = 2,7.8,04 É y=6,3.0,159, determine o valor de a) 2x b)5y c) O triplo de u d) x.y e) x+u f) x-y​

Answer 1

Resposta:

x=2,7 × 8,04

x= 21,708

y=6,3 × 0,159

y=1,0017

a)

2x=2.(21,708) =43,416

b)

5y=5.(1,0017)=5,0085

c)

3y=3.(1,0017)=3,0051

d)

x . y= (21,708) × (1,0017)= 21,7449036

e)

x+y= 21,708 + 1,0017= 22,7097

f)

x-y= 21,708 - 1,0017 = 20,7063
