Question

evaluate the expression.
(5.5 × 10⁻³) ÷ (5 × 10⁻⁴)
? × 10

Explanation:

Step1: Split into two separate divisions

$\frac{5.5}{5} \times \frac{10^{-3}}{10^{-4}}$

Step2: Calculate coefficient division

$\frac{5.5}{5} = 1.1$

Step3: Calculate power of 10 division

$\frac{10^{-3}}{10^{-4}} = 10^{-3 - (-4)} = 10^{1}$

Step4: Multiply the two results

$1.1 \times 10^{1}$

Answer:

$1.1 \times 10^{1}$
