Final answer:
The equation 83 — 10^4 = 83,000 is incorrect because 10^4 represents 10,000, and subtracting that from 83 does not yield 83,000, but rather -9,917.
Step-by-step explanation:
The equation 83 — 10^4 = 83,000 is incorrect. The expression 10^4 stands for 10 raised to the power of 4, which equals 10,000. Therefore, subtracting 10,000 from 83 would not give you 83,000, but rather -9,917. When evaluating such expressions, remember that the caret symbol '^' represents exponentiation, and the exponent indicates how many times to multiply the base (which is 10 in this case) by itself. If you indeed wanted to express the number 83,000 using powers of ten, you could write it as 8.3 × 10^4.
