Answer» Correct Answer - Option 1 : - 2 Given: 2x+4 - 2x+2 = 3 Formula used: a^{m +}ⁿ= a^m.aⁿ Calculation: 2x+4 - 2x+2 = 3 ⇒ 2^x.2⁴ - 2^x.2² = 3 ⇒ 2^x(2⁴ - 2²) = 3 ⇒ 2^x = 1/4 ⇒ 2^x= 2^{- 2} ⇒ x = - 2 ∴ value of x is -2.

423.

If 2x+4 - 2x+2 = 3 then value of x is1. - 22. 23. 14. - 1

Answer» Correct Answer - Option 1 : - 2

Given:

2x+4 - 2x+2 = 3

Formula used:

a^{m +}ⁿ= a^m.aⁿ

Calculation:

2x+4 - 2x+2 = 3

⇒ 2^x.2⁴ - 2^x.2² = 3

⇒ 2^x(2⁴ - 2²) = 3

⇒ 2^x = 1/4

⇒ 2^x= 2^{- 2}

⇒ x = - 2

For what value of n, the sum of digits in the number (10n + 1) is 2?1. For n = 0 only2. For any whole number n3. For any positive integer n only4. For any real number n

Answer» Correct Answer - Option 2 : For any whole number n

Given:

The sum of digits in the number (10n + 1) is 2

Calculation:

(10n + 1) = 2

According to the question:

If n= 0

⇒ (10⁰ + 1) = 1 + 1

⇒ 2

If n= 1

⇒ (10¹ + 1) = 10 + 1 = 11

⇒ Sum of digits = 1 + 1 = 2

If n= 2

⇒ (10² + 1) = 100 + 1 = 101

⇒ Sum of digits = 1 + 0 + 1 = 2

This means that for any whole number n, the sum of digits is 2.

Hence, option 2 is the correct answer.

Answer» Correct Answer - Option 3 : \(1\frac{7}{8}\)

Given:

5 \(\frac{3}{4}\) + x + 2 \(\frac{1}{2}\) = 10 \(\frac{1}{8}\)

Calculation:

⇒ 5 \(\frac{3}{4}\) + x + 2 \(\frac{1}{2}\) = 10 \(\frac{1}{8}\)

⇒ 23/4 + x + 5/2 = 81/8

⇒ 33/4 + x = 81/8

⇒ x = 15/8 = \(1\frac{7}{8}\)

∴ The value of x is \(1\frac{7}{8}\)
