Question

To open the treasure box, the following expression needs to be solved:
$\frac{1.53\times {10}^7}{1.8\times {10}^3}$

The value of the expression is .

• A. $8.5\times {10}^4$
• B. $0.85\times {10}^{10}$
• C. $8.5\times {10}^5$
• D. $8.5\times {10}^3$

Answer 1

The correct option is D $8.5\times {10}^3$

The given expression is $\frac{1.53\times {10}^7}{1.8\times {10}^3}$

$⟹\frac{1.53}{1.8}\times \frac{{10}^7}{{10}^3}$
$⟹0.85\times {10}^{7-3}$
$⟹0.85\times {10}^4$
$⟹8.5\times {10}^3$

The value of the expresssion to open the treasure box is $8.5\times {10}^3$.
