Question

calculate.
$(4.3 \times 10^5)(2 \times 10^2)$
write your answer in scientific notation.

Explanation:

Step1: Multiply the coefficients

$4.3 \times 2 = 8.6$

Step2: Add the exponents of 10

$10^{5} \times 10^{2} = 10^{5+2} = 10^{7}$

Step3: Combine the results

Multiply the product of coefficients and the product of powers of 10

Answer:

$8.6 \times 10^{7}$
