What is the scientific notation of (1.4x10¹)(8x10⁴) ?

Answer 1

(1.4x10¹) = 14 and (8x10⁴) = 80000

(1.4x10¹)(8x10⁴) = 14 x 80000

= 1.12x10⁶

Therefore, the scientific notation of (1.4x10¹)(8x10⁴) is 1.12x10⁶.

Answer 2

(1.4 * 8) * 10^(1+4) = 11.2 *10^5 = 1.12 * 10^6

Answer 3

That's correct! This is another way to simplify and calculate the expression. The final answer is still 1.12x10⁶ in scientific notation.
