Question

(7x7) (10^-6 x 10^-6) expressed in scientific notation WITH EXPLANATION

Answer 1

Explanation:

In exponent multiplication, if base is same, then add the powers

`(7 * 7) * (10^(-6)*10^(-6))= 49 * {10^((-6) + (-6))\\\\=( 4.9*10^(1) )* 10^(-12)\\\\= 4.9 * 10^(1 + (-12))\\\\= 4.9 * 10^(-11)`
