Which is the best estimate for 6.3×10 to the second power times 9.9×10 to the 3rd power written in scientific notation

viva [34]

Answer:

in scientific notation, the expression can be written as 6.237 x 10⁶

Step-by-step explanation:

Given;

6.3×10 to the second power times 9.9×10 to the 3rd power

Using scientific notation, it can be interpreted as;

$(6.3 \times 10^2) \times (9.9 \times 10^3)$

This can be simplified as;

$(6.3 \times 10^2) \times (9.9 \times 10^3) = (6.3\times 9.9)\times 10^{2+3}\\\\= 62.37\times 10^5 = 6.237\times 10^6$

Therefore, in scientific notation, the expression can be written as 6.237 x 10⁶
