Answer 1

The decimal equivalent of a hexadecimal

number 2A is 42.

Explanation: We know that, for converting hexadecimal to decimal we will start from the right side of the digit and multiply it with 16, having 16 raised to the power 0, with the increase in digits we will increase the power to 1,2,3,4... so on according to the digit,

2A = (A × 16^0) + (2 × 16^1)

2A = (10 × 1 ) + (2 × 16)

2A = 10 + 32

2A = 42

Note: The value of A in hexadecimal is assigned as 10.
