Question

Multiply and write scientific notation for the result:
(7.1 ×〖10〗^(-7) )(8.6 ×〖10〗^(-5))

Answer 1

\[61.06 \times 10^{-12}\]

Answer 2

7.1 x 10^(-7) = 7.1 x (10)^-5 x (10^-2) = 0.071 x 10^-5
(7.1 ×〖10〗^(-7) )(8.6 ×〖10〗^(-5)) = (0.071 x 10^-5 ) (8.6 x 10^-5)
= 0.6106 x 10^-10
= 61.06 x 10^-12
