Final answer:
In plain text, the expression 2³ + 5 * 4 translates to 'two raised to the third power plus five times four'. You would first calculate 2³ as 2 x 2 x 2, which is 8, and then perform the multiplication 5 * 4 to get 20. The final sum of these two calculations is 28.
Step-by-step explanation:
The expression 2³ + 5 * 4 in plain text is 'two raised to the third power plus five times four'. In mathematics, the caret sign (^) is often used to indicate exponentiation, so 2³ means 2 raised to the power of 3. This can be calculated by multiplying 2 by itself three times: 2 x 2 x 2, which equals 8. The second part of the expression is 5 * 4, which means five times four. This equals 20.
To evaluate the entire expression, you perform each operation in the correct order according to the order of operations, which means you handle the exponentiation before multiplication and addition. Thus, 2³ + 5 * 4 equates to 8 + 20, which then results in 28.
Recall that when dealing with exponentiation, such as squaring or cubing of exponentials, if we had an exponential term like 4³, we would calculate it in the same way we did with 2³ by multiplying 4 by itself three times.
