Question

What is the quotient of (6.591x10^7) divided by (8.45x10^2) expressed in scientific notation?

Answer 1

Explanation:

remember,

(ab)/(cd) = a/c × b/d = a/d × b/c

and

x^a/x^b = x^(a-b)

so,

(6.591 × 10⁷) / (8.45 × 10²) = 6.591/8.45 × 10⁷/10² =

= 6.591/8.45 × 10⁵ =

= 0.78 × 10⁵ = 7.8 × 10⁴
