Answer 1

Resposta:

a)0,0003×0,001475=             ​​a)0.0000004425, =  4,425 x 10⁺³

b)0,0043 : 0,000025=           b)172 =  1,72 x 10⁺²

c)0,0000057×0,000425=      c) 2,4225x10⁻⁹

d)1,975.10-⁷ : 3,35.10-³=  0,0000001975 ÷ 0,00335 = 0.00005 =5 x 10⁻⁵

e)5,365.10⁹ - 7,40.10⁹=    5365000000-7400000000     -2035000000= -2,035 x 10⁺⁹

f)0,325.10⁵ + 2,4.10⁵=272500=2,725 x 10⁺⁵

g)0,0000345×0,000195= 0,0000000067275 =6,7275 x 10⁻⁹

h)1,36.10-⁶ : 2,2.10³= 0.00061 = 6,1 x 10⁻⁴

i)=0,00000000012×0,000000325=     3,9E-17

j)0,00000045×0,00000000265=0.00000045ₓ  2.65E-9 = 1.1925E-15
