Question

(5x 10-6)(3x 10-4)(5x 10-6) (3 x 10 - 4) =PLS HELP IT’S DUE TNNNN !

Answer 1

we can multiply the normal numbers on the one hand and the scientific notation on the other hand

so

$\begin{gathered} (5\times3)(10^{-6}\times10^{-4}) \\ (15)(10^{-6+(-4)}) \\ =15\times10^{-10}=1.5\times10^{-9} \end{gathered}$
