Answer:
[tex]1.53\times10^4[/tex]
Step-by-step explanation:
The given expression is:
[tex]6.4\times(10*10*10)+1.4\times(10*10*10)+7.5\times(10*10*10)[/tex]
We apply the distributive property to get:
[tex](6.4+1.4+7.5)\times(10*10*10)[/tex]
We add to get:
[tex](6.4+1.4+7.5)\times(10*10*10)[/tex]
[tex]15.3\times10^3[/tex]
In scientific notation, we have
[tex]1.53\times10^4[/tex]
