Answer:
-2
Step-by-step explanation:
We have to multiply 10 and
Here we have to distribute the negative sign.
Distributive property = -(a) = -a
Using the above property, we get =
Now we have to multiply 10 and
= 10 ×
=
=
Now we have to divide -10 by 5.
= -2
Answer:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
Step-by-step explanation:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
To prove this conjecture
unit digit = 6
hence the property is true for ; n = 1 and n = 2 and also for every odd and even number ( i.e. from 1 to 8 )
