simplify 2.1(4pi*10^{-7})

simplify

2.1 (4 π \cdot 1 0^{- 7})

2.63894 E - 6

Solution steps

2.1 (4 π 1 0^{- 7})

Apply exponent rule:

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

= 4 \cdot 2.1 π \frac{1}{1 0 ^{7}}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= 2.1 \cdot \frac{1 \cdot 4 π}{1 0 ^{7}}

\frac{1 \cdot 4 π}{1 0 ^{7}} = \frac{π}{2500000}

= 2.1 \cdot \frac{π}{2500000}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{π 2.1}{2500000}

Multiply the numbers:

3.14159 \dots \cdot 2.1 = 6.59734 \dots

= \frac{6.59734 \dots}{2500000}

Divide the numbers:

\frac{6.59734 \dots}{2500000} = 2.63894 E - 6

= 2.63894 E - 6
