If your question means;
( 6 ∙ 104 + 3 ∙ 104 ) 3 ∙ 102
then
( 6 ∙ 104 + 3 ∙ 104 ) 3 ∙ 102 = 9 ∙ 104 ∙ 3 ∙ 102 = 286416 = 2.86416 ∙ 10⁵
But if your question means:
( 6 ∙ 10⁴ + 3 ∙ 10⁴ ) ∙ 3 ∙ 10²
then
( 6 ∙ 10⁴ + 3 ∙ 10⁴ ) ∙ 3 ∙ 10² = 9 ∙ 10⁴ ∙ 3 ∙ 10² = 9 ∙ 3 ∙ 10⁴ ∙ 10² =
27 ∙ 10⁴ ⁺ ² = 2.7 ∙ 10 ∙ 10⁶ = 2.7 ∙ 10¹ ∙ 10⁶ = 2.7 ∙ 10¹ ⁺ ⁶ = 2.7 ∙ 10⁷
(6 × 104 + 3 × 104)(3 × 102)
What is the value of the expression in scientific notation?

(6 * 10^4 + 3 * 10^4)(3 * 10^2)
= 9*10^4(3*10^2)
= 27*10^6
= 2.7 * 10^7
= 9*10^4(3*10^2)
= 27*10^6
= 2.7 * 10^7
