simplify (40)(1.6*10^{-19})

simplify

(40) (1.6 \cdot 1 0^{- 19})

\frac{1}{5 ^{19} \cdot 8192}

Decimal Notation

6.4 E - 18

Solution steps

(40) (1.6 \cdot 1 0^{- 19})

Apply rule:

(a) = a

(40) = 40

= 40 \cdot 1.6 \cdot 1 0^{- 19}

Multiply the numbers:

40 \cdot 1.6 = 64

= 64 \cdot 1 0^{- 19}

= 1 0^{- 19} \cdot 64

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

1 0^{- 19} = \frac{1}{1 0 ^{19}}

= \frac{1}{1 0 ^{19}} \cdot 64

\frac{1}{1 0 ^{19}} \cdot 64 = \frac{1}{5 ^{19} \cdot 8192}

= \frac{1}{5 ^{19} \cdot 8192}

3.1 \cdot 1 0^{- 11} m

8 e^{- 100 (5)} (3.2)

e^{- m t} (a sin (wt) + b cos (wt))

- 2.18 \cdot 1 0^{- 18} (1 - 0)
