2) x^18
3) 0

Answer 2

I'm a bit doubtful about the last question -- is it 4*0 or 4x^0 ?

Answer 3

its 4^0

Answer 4

my bad 4x^0

Answer 5

K .. so 4x^0 = 4 * 1 = 4 ..

Since , a^0 = 1 (Law of exponents)

Answer 6

thanks i never knew there was a law of exponets.

Answer 7

but wouldn't it be like 4x? or did the x get canceled out?

Answer 8

no, it's just a law.. anything to the power 0 , becomes 1 .. i.e.. a^0 = 1

there's one more law that anything to the power one is the same thing .
i.e a^1 = a ..

Hope you got your answer :)
