simplify (3910^4)(1.6*10^{-19})

simplify

(39 \cdot 1 0^{4}) \cdot (1.6 \cdot 1 0^{- 19})

\frac{39}{5 ^{16} \cdot 4096}

Solution steps

(39 \cdot 1 0^{4}) (1.6 \cdot 1 0^{- 19})

39 \cdot 1 0^{4} = 390000

= 390000 \cdot 1.6 \cdot 1 0^{- 19}

Apply exponent rule:

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

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

= 390000 \cdot 1.6 \cdot \frac{1}{1 0 ^{19}}

Multiply the numbers:

390000 \cdot 1.6 = 624000

= 624000 \cdot \frac{1}{1 0 ^{19}}

624000 \cdot \frac{1}{1 0 ^{19}} = \frac{39}{5 ^{16} \cdot 4096}

= \frac{39}{5 ^{16} \cdot 4096}

- 0.3 \cdot 1 0^{- 6}

\frac{e ^{x - \frac{1}{2}}}{e ^{- \frac{1}{2} y^{2}}}

(\frac{1}{2}) \cdot (9.8 m s^{2}) \cdot (2.85 s)^{2}

1000 (1 + \frac{0.15}{12})^{- 6}

(7.12 \cdot 1 0^{- 4}) (77.6)
