Solution

simplify

4 \cdot 1 0^{- 4}

\frac{1}{2500}

Decimal Notation

0.0004

Solution steps

4 \cdot 1 0^{- 4}

Apply exponent rule:

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

1 0^{- 4} = \frac{1}{1 0 ^{4}}

= 4 \cdot \frac{1}{1 0 ^{4}}

1 0^{4} = 10000

= 4 \cdot \frac{1}{10000}

4 \cdot \frac{1}{10000} = \frac{1}{2500}

= \frac{1}{2500}

\frac{x ^{2} - 1}{x ^{2} + 10 x + 9}

\frac{3 x + 3 y}{20 x y} + \frac{3 x - 3 y}{20 x y}

5^{2} + 7^{2}

\frac{6 x ^{2} - x y - 2 y ^{2}}{y + 2 x}

\frac{4 ^{2} 3}{4}
