Answer :
The value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889
Solution:
Given that:
[tex]2^{-3} \times 3^{-2}[/tex]
We have to find the value of expression
We know that,
[tex]a^{-n} = \frac{1}{a^n}[/tex]
Therefore,
[tex]2^{-3} \times 3^{-2} = \frac{1}{2^3} \times \frac{1}{3^2}[/tex]
We know that,
[tex]a^2 = a \times a[/tex]
Similarly,
[tex]2^{-3} \times 3^{-2} = \frac{1}{2 \times 2 \times 2} \times \frac{1}{3 \times 3}\\\\Simplify\\\\2^{-3} \times 3^{-2} = \frac{1}{8} \times \frac{1}{9}\\\\2^{-3} \times 3^{-2} = \frac{1}{72}\\\\Simplify\\\\2^{-3} \times 3^{-2} = 0.013889[/tex]
Thus value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889
