Question

$\frac{[(4.000) ^{2} ][300]}{0,02} =$

Answer 1

Olá.

$\mathsf{\dfrac{[(4.000)^2]\cdot[300]}{0,02}=\dfrac{[(4x10^3)^2]\cdot[3x10^{2}]}{2x10^{-2}}=\dfrac{16x10^6\cdot3x10^2}{2x10^{-2}}=}\\\\\\\mathsf{\dfrac{48x10^{6+2}}{2x10^{-2}}=\dfrac{48x10^{8}}{2x10^{-2}}=(48/2)x(10^{8-(-2)})=\boxed{\mathsf{24x10^{10}}}}$

Bons estudos.
