+1

Decimal Notation

0.0016

Solution steps

5^{2} \cdot 5^{- 6}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

5^{2} \cdot 5^{- 6} = 5^{2 - 6}

= 5^{2 - 6}

Subtract the numbers:

2 - 6 = - 4

= 5^{- 4}

Apply exponent rule:

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

5^{- 4} = \frac{1}{5 ^{4}}

= \frac{1}{5 ^{4}}

5^{4} = 625

= \frac{1}{625}
