Question

(5.391 ´ 10-7) + (2.5531 ´ 10-6) =

Answer 1

Answer:

$(5.391 * 10^{-7}) + (2.5531 * 10^{-6}) = 3.0922 * 10^{-6}$

Explanation:

Given

$(5.391 * 10^{-7}) + (2.5531 * 10^{-6})$

Required

Solve

$(5.391 * 10^{-7}) + (2.5531 * 10^{-6})$

Remove the brackets

$5.391 * 10^{-7} + 2.5531 * 10^{-6}$

Express $10^{-7}$ as $10^{-1-6}$

$5.391 * 10^{-1-6} + 2.5531 * 10^{-6}$

Apply law of indices

$5.391 * 10^{-1} * 10^{-6} + 2.5531 * 10^{-6}$

$0.5391 * 10^{-6} + 2.5531 * 10^{-6}$

Factorize:

$(0.5391 + 2.5531)10^{-6}$

$(3.0922)10^{-6}$

Remove bracket

$3.0922 * 10^{-6}$

Hence:

$(5.391 * 10^{-7}) + (2.5531 * 10^{-6}) = 3.0922 * 10^{-6}$
