(3.0*10^-9)²
You asked:
Evaluate the expression: \({\left( 3.0 \cdot {10}^{-9} \right)}^{2}\)
MathBot Answer:
\[{\left( 3.0 \cdot {10}^{-9} \right)}^{2} = \frac{9}{1000000000000000000} = 0.000000000000000009\]
\[\begin{aligned}{\left( 3.0 \cdot {10}^{-9} \right)}^{2}& = \left(3 \cdot \frac{1}{10^{9}}\right)^{2}\\& = \left(\frac{3}{1000000000}\right)^{2}\\& = \frac{9}{1000000000000000000}\end{aligned}\]
