Question

Turn this into scientific notation and standard form 

Answer 1

(8.1x 10⁴ )/(1.8 x10^-4) = ( 8.1/1.8)x 10^4-(-4)

= 4.5x10⁸

 

Answer 2

I hope, Cassidy, the answer is still actual for you.
    8.1×10⁴              8.1×10⁴ ×10⁴         8.1×10⁸  
    1.8×10^-4                    1.8                 1.8 
8.1/1.8 = 4.5   --->  4.5×10⁸  —  scientific notation     
81000 / 0.00018 = 450 000 000 — standard notation
