Answer: The last option.
Step-by-step explanation:
1. By definition a number written in scientific notation has the following form:
Where <em>a</em> is the coefficient (which is a number between 1 and 10 but not including 10) and <em>b</em> is the exponent (It must be an integer).
2. The decimal point of the coefficient must be wrriten after the first digit.
3. Based on this information, the number shown in the last option has the decimal point after the second digit, therefore, it is not written is scientific notation.
Answer:
3x3-45÷(4+1) is 0.
Step-by-step explanation:
We have to do order of operations so we follow PEMDAS:
P is for Parentheses so we do what's in parentheses first:
(4+1)=5
E is for Exponents but we don't have exponents.
Next is M and D for Multiplication and Division. We have division before multiplication so we should do division first:
45÷5=9
We now have multiplication:
3x3=9
Now we have A and S for addition and subtraction
We don't have addition so we'll do subtraction:
9-9=0
The final answer is 0.
Hope this helps! :)
