Step-by-step explanation:
In simplest radical form
= √-3
= -3^(1/2)
or
= √-3
= √3i
i is imaginary number, you can write it if you find a negative number in a square root
=(f-g)(x)
=f(x)-g(x)
=x+6-(x-6)
=x+6-x+6
=12
Answer:
A. 8100
Step-by-step explanation:
85 x 86
To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.
85*100 = 8500
Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.
