\( \int_a^b f(x)\,dx = F(b) – F(a) \)-

\( E^2 = p^2c^2 + m^2c^4 \)

**১।**

নিচের সংখ্যাগুলোর মধ্যে কোনটি বৃহত্তম?

\( \sqrt{0.09} \), \( \sqrt[3]{0.008} \), \( 0.2\dot{3} \) এবং \( (0.2)^2 \)

 

ক) \( \sqrt{0.09} \)

খ) \( \sqrt[3]{0.008} \)

গ) \( 0.2\dot{3} \)

ঘ) \( (0.2)^2 \)

 

**সঠিক উত্তর:** ক) \( \sqrt{0.09} \)

**ব্যাখ্যা:** প্রতিটি সংখ্যাকে দশমিকে রূপান্তর করি:

(ক) \( \sqrt{0.09} = \sqrt{\dfrac{9}{100}} = \dfrac{3}{10} = 0.3 \)

(খ) \( \sqrt[3]{0.008} = \sqrt[3]{\dfrac{8}{1000}} = \dfrac{2}{10} = 0.2 \)

(গ) \( 0.2\dot{3} = \dfrac{23-2}{90} = \dfrac{21}{90} = \dfrac{7}{30} \approx 0.233… \)

(ঘ) \( (0.2)^2 = 0.04 \)

সংখ্যাগুলো হলো: \( 0.3 \), \( 0.2 \), \( 0.233… \), \( 0.04 \)। এদের মধ্যে বৃহত্তম \( 0.3 \)।

1. What Is a Digital Marketing Strategy?

A digital marketing strategy is a structured action plan that uses online channels to achieve business goals. These channels include search engines, content platforms, social media, email marketing, and paid ads.

Instead of random posting or inconsistent campaigns, a clear marketing plan ensures every effort supports measurable growth. It aligns your business objectives with digital tactics so that every campaign has a purpose and a clear outcome.

When properly implemented, this approach allows businesses to compete effectively, regardless of their size or industry.

2. Why It Matters for Business Growth

Businesses that create a documented online marketing plan see better performance. According to research from HubSpot (https://www.hubspot.com), companies with clear strategies are more likely to generate higher-quality leads and improve conversion rates.

A focused approach helps you:

• Reach the right audience

• Improve engagement

• Increase conversion rates

• Maximize return on investment

• Build long-term customer relationships

Without a roadmap, marketing efforts often become inconsistent and ineffective. A strong plan ensures steady progress and sustainable growth.

3. Audience Research and Positioning

Understanding your target audience is the foundation of success. Identify demographics, behavior patterns, interests, and online habits. The better you understand your audience, the more personalized and effective your campaigns will be.

You can also study competitors using tools like Moz (https://moz.com) to discover keyword opportunities and content gaps. Research helps you uncover what works in your industry and how you can differentiate your brand.

Clear positioning allows your business to stand out in a competitive market and attract customers who truly value your offerings.

Careful budget management and performance tracking ensure better returns from advertising investments.

Tracking data is critical for long-term success. Monitor key metrics such as:
