Final answer:
To calculate the value of the expression 1.23 + (-1.9)4 to the nearest tenth, we calculate each term independently, then add the results, rounding the sum, 14.7601, to 14.8.
Step-by-step explanation:
To find the value of the expression 1.23 + (-1.9)4 to the nearest tenth,
we need to calculate each term separately and then add the results. 1.23 equals 1.728 when calculated.
The term (-1.9)4 equals 13.0321 because raising a negative number to an even exponent results in a positive number.
We then add 1.728 to 13.0321 to get 14.7601.
Since the question asks for the nearest tenth, we look at the hundredths place which is 6 (more than 5),
so we round up the tenths place to 14.8 as our final answer.
