Question

1)Efetue as operações com notação científica a seguir​

Answer 1

Explicação passo-a-passo:

f) $\sf 6\cdot10^4\times4\cdot10^2=(6\cdot4)\times(10^{4+2})$

$\sf 6\cdot10^4\times4\cdot10^2=24\times10^6$

$\sf 6\cdot10^4\times4\cdot10^2=2,4\cdot10^7$

g) $\sf 3\cdot10^3\times7\cdot10^6=(3\cdot7)\times(10^{3+6})$

$\sf 3\cdot10^3\times7\cdot10^6=21\times10^9$

$\sf 3\cdot10^3\times7\cdot10^6=2,1\cdot10^{10}$

h) $\sf 15\cdot10^6\div3\cdot10^3=(15\div3)\times(10^{6-3})$

$\sf 15\cdot10^6\div3\cdot10^3=5\cdot10^3$

i) $\sf 24\cdot10^{27}\div6\cdot10^9=(24\div6)\times(10^{27-9})$

$\sf 24\cdot10^{27}\div6\cdot10^9=4\cdot10^{18}$
