Given:


(4*10^8)^(-2)

Aim:

We need to write the given expression in scientific notation.

Step-by-step explanation:


Use\text{ \lparen a}* b)^n=a^n* b^n.


(4*10^8)^(-2)=4^(-2)*(10^8)^(-2)


Use\text{ \lparen a}^n)^m=a^(n* m).


(4*10^8)^(-2)=4^(-2)*10^(-16)
Use\text{ a}^(-n)=(1)/(a^n)


(4*10^8)^(-2)=(1)/(4^2)*10^(-16)


(4*10^8)^(-2)=(1)/(16)*10^(-16)


(4*10^8)^(-2)=0.0625*10^(-16)
Use\text{ -16=2-18.}


(4*10^8)^(-2)=0.0625*10^(2-18)


(4*10^8)^(-2)=0.0625*100*10^(-18)


(4*10^8)^(-2)=6.25*10^(-18)

Final answer:


(4*10^8)^(-2)=6.25*10^(-18)
