Negative logarithm divide by whole number
Answers
Answer:
When you divide a positive number by a negative number then the quotient is also negative. When you divide two negative numbers then the quotient is positive.There is one very important exception to the rule that multiplying or dividing an inequality is the same as multiplying or dividing an equation. Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.A negative logarithm means how many times to divide by the number. We can have just one divide: Example: What is log8(0.125) ... ? Well, 1 ÷ 8 = 0.125, So log8(0.125) = −1.The only numbers you can plug into a logarithm are positive numbers not equal to 1. ... If you raise a negative number to a positive number that's not an integer, but instead a fraction or a decimal, you might end up with a negative number underneath a square root.
