-( -2(-7) + 2*6i )

-( 14 + 12i)

-14 - 12i

Write 4,706 × 10 11 in standard notation
aleksandrvk [35]

I am guessing that is 1011? Just to be safe, I will do 4706*10 and 4706*1011.


4706*10: So, 4,706 times 10 is 47060

4706*1011: 4,706 times 1011 is 4757766

Standard notation is the normal way of writing numbers. So the answers I wrote are all in Standard notation.
