9514 1404 393

Answer:

 n = 6

Step-by-step explanation:

Perhaps you want n for ...

  4\times10^n=4\,000\,000\\\\10^n=1\,000\,000 \qquad\text{divide by 4}\\\\n=6\qquad\text{count the zeros}

__

You know that multiplying by 10 appends a 0 to the right end of an integer number. So, a 1 with 6 zeros has been multiplied by 10 six times. The exponent signifies the number of times the factor is repeated. The exponent, n, is 6.

subtract both sides by 500 to get -4x=-232

then divide both sides by -4 to get x=58
