In your own words describe the steps you take to round a decimal

Step-by-step explanation:

Lets say that I have 9.6+78.9 to estimate, we need to just calculate what it rounds up to, 9.6 rounds up to 10 and 78.9 rounds of to 79, our answer will be at round 89, this is the basic way of how to round it up. Btw the answer is 88.5

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
