simplify 1.263.210^{-19}

simplify

1.26 \cdot 3.2 \cdot 1 0^{- 19}

\frac{63}{5 ^{19} \cdot 8192000}

Solution steps

1.26 \cdot 3.2 \cdot 1 0^{- 19}

Multiply the numbers:

1.26 \cdot 3.2 = 4.032

= 4.032 \cdot 1 0^{- 19}

= 1 0^{- 19} \cdot 4.032

Apply exponent rule:

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

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

= \frac{1}{1 0 ^{19}} \cdot 4.032

\frac{1}{1 0 ^{19}} \cdot 4.032 = \frac{4.032}{1 0 ^{19}}

= \frac{4.032}{1 0 ^{19}}

\frac{4.032}{1 0 ^{19}} = \frac{4032}{1000 \cdot 1 0 ^{19}}

= \frac{4032}{1000 \cdot 1 0 ^{19}}

Factor the number:

4032 = 8 \cdot 504

= \frac{8 \cdot 504}{1000 \cdot 1 0 ^{19}}

Factor the number:

1000 = 8 \cdot 125

= \frac{8 \cdot 504}{8 \cdot 125 \cdot 1 0 ^{19}}

Cancel the common factor:

8

= \frac{504}{125 \cdot 1 0 ^{19}}

Factor

504 : 2^{3} \cdot 63

= \frac{2 ^{3} \cdot 63}{125 \cdot 1 0 ^{19}}

Factor

1 0^{19} : 2^{19} \cdot 5^{19}

= \frac{2 ^{3} \cdot 63}{125 \cdot 2 ^{19} \cdot 5 ^{19}}

\frac{2 ^{3}}{2 ^{19}} = \frac{1}{2 ^{16}}

= \frac{63}{125 \cdot 2 ^{16} \cdot 5 ^{19}}

125 \cdot 2^{16} \cdot 5^{19} = 5^{19} \cdot 8192000

= \frac{63}{5 ^{19} \cdot 8192000}

(2.733 \cdot 1 0^{- 31}) \cdot (3 \cdot 1 0^{8})

e^{3} (e^{4})^{2}

\frac{0.307 - 7 \cdot 1 0 ^{- 3}}{1.27} \cdot 3.2 \cdot 1 0^{- 5}

x^{2} \cdot x^{π} \cdot (- 1)^{\frac{1}{π}}

\frac{[ 3 ^{3} - ( - 5 ) ^{2} ] ^{2}}{{ [ ( - 1 ) ^{2} ] ^{2} } ^{2}}
