$19.999452$ $19.999452$

Explanation:

According to B.E.D.M.A.S., simplify $5.48 \cdot 10^{- 4}$ $5.48*10^(-4)$ first, since it deals with multiplication. Recall that $10^{- 4}$ $10^(-4)$ means dividing by $10^{4}$ $10^4$ .

$20 - 5.48 \cdot 10^{- 4}$ $20-5.48*10^(-4)$

$= 20 - 0.000548$ $=20-0.000548$

Solve.

$= 19.999452$ $=19.999452$
