Question

(1.6 x 10^12) ÷ (8.01 x 10^23)

Answer 1

Answer: $=1.9975031211\times10^{20}$

Step-by-step explanation:

The given expression : $(1.6\times10^2)\div(8.01\times10^{23})$

To divide the above expression, we need to divide the coefficients and exponents separately, then we have

$(1.6\div8.01)(10^2\div10^{23})$

Using the law of exponents to divide exponents number with same base (10):

$a^m\div a^n=a^{m-n}$

$\Rightarrow(1.6\div8.01)(10^2\div10^{23})=(0.19975031211)(10^{2-23})\\\\=(1.9975031211\times10)(10^{-21})\\\\=(1.9975031211)(106{-21+1})\\\\=1.9975031211\times10^{20}$

Answer 2

(1.6 x 10^12) ÷ (8.01 x 10^23)
(1.6 x 10^12) = 1.6e + 12
(8.01 x 10^23) = 8.01e + 23
(1.6e + 12) + (8.01e + 23) =
61.123
