Solution to a:
Given Binary Number,
= (1010 010)₂
We have to find out the decimal equivalent of the given number,
So, decimal equivalent will be,
= (1 × 2⁶) + (0 × 2⁵) + (1 × 2⁴) + (0 × 2³) + (0 × 2²) + (1 × 2¹) + (0 × 2⁰)
= 64 + 0 + 16 + 0 + 0 + 2 + 0
= (82)₁₀ ★
Answer:
- (1010 010)₂ = (82)₁₀
Solution to b:
Given Binary Number,
= (1111 100)₂
Decimal equivalent will be,
= (1 × 2⁶) + (1 × 2⁵) + (1 × 2⁴) + (1 × 2³) + (1 × 2²) + (0 × 2¹) + (0 × 2⁰)
= 64 + 32 + 16 + 8 + 4 + 0 + 0
= (124)₁₀ ★
Answer:
- (1111 100)₂ = (124)₁₀
