Question

Pls change this to decimal number 1011111 base 2​

Answer 1

Answer:

95

Step-by-step explanation:

1. First, the binary to decimal formula is:  

• decimal = $d_0*2^0 + d_1 *2^1 + d+2*2^2+..$  

2. Now, let's apply it:

• $(1011111 )_2= (1 *2^6) + (0 *2^5) + (1*2^4) + (1*2^3) + (1 *2^2) + (1 *2^1) + (1*2^0)$

• $1(64) + 0(32) + 1(16)+1(8)+1(4)+1(2)+1(1)$
• $64 + 0 + 16 + 8 + 4 + 2 + 1$
• $80 + 8 + 4 + 2 + 1$
• $88 + 4 + 2 + 1$
• $92 + 2 + 1$
• $94 + 1$
• $95$

Therefore, the answer is 95.
