A. 1.941 x 1012

B. 6.801 x 1012

C. 1.941 x 100

D. 6.801 x 100

Answer 1

Answer:

$\sf A. \quad1.941 \times 10^{12}$

Step-by-step explanation:

To find the difference, subtract the second expression from the first expression:

$\implies \sf 7.341 \times 10^{12}-5.4 \times 10^{12}$

Factor out 10¹² by applying the Distributive Property of Subtraction in reverse:

$\implies \sf 10^{12}(7.341-5.4)$

Carry out the operation in the parentheses:

$\implies \sf 10^{12}(1.941)$

Rewrite in the original form:

$\implies \sf 1.941 \times 10^{12}$
