-15+4/5 (15e-10)-10e

Question

the answers are
2e+23
2e-23
-2e+23
-2e-24

Answer 1

To simplify the expression, we first perform the operations inside parentheses and brackets:
-15 + 4/5 - 10e - 10e
Next, we combine like terms:
-15 + 4/5 - 20e
To add and subtract e-terms, they must have the same base (e in this case). The two given answers that have the same base are 2e+23 and -2e+23.
None of the given answers has the same base as -20e.
Therefore, the expression cannot be simplified to any of the given answers.
