Question

find (5.3x10^3)-(8x10^2)

Answer 1

Step-by-step explanation:

(5.3 * 10³) - (8 * 10²)

= (5.3 * 10³) - (0.8 * 10³)

= 4.5 * 10³

= 4,500.

Answer 2

Answer:

$(5.3 \times {10}^{3} ) - (8 \times {10}^{2} ) \\ = (5.3 \times {10}^{3} ) - (0.8 \times {10}^{3} ) \\ = (5.3 - 0.8) \times {10}^{3} \\ = 4.5 \times {10}^{3} \\ = \boxed{4500}$

4500 is the right answer.
