Sergeeva-Olga [200]

Answer:

$1.53\times10^4$

Step-by-step explanation:

The given expression is:

$6.4\times(10*10*10)+1.4\times(10*10*10)+7.5\times(10*10*10)$

We apply the distributive property to get:

$(6.4+1.4+7.5)\times(10*10*10)$

We add to get:

$(6.4+1.4+7.5)\times(10*10*10)$

$15.3\times10^3$

In scientific notation, we have

$1.53\times10^4$
