Pemdas? OK so how I would remember it by is "Please Excuse My Dear Aunt Sally"
So.. Parenthesis, Exponent(s), Multiplication, Division, Addition, Subtraction..
Example~~~~~
(
+ 4) ×12÷4 - 1= ? so first do parenthesis and then the exponents then add it to 4 and the divide 12 and 4 and then subtract 1 which is 2.. Then after take two and 13 and multiply which is 26~
Hope this helps! :)
Answer:
k>-10
Step-by-step explanation:
2-9k>-88
To even out the left side, we must subtract 2 from both sides.
9k>-90
Now we divide by 9 to get 1k or k.
k>-10
Answer:
C
Step-by-step explanation:
First things first, we need to simplify (8^2)^-4. When a number is raised to a power, and the result of that is raised to another power, the two powers can be multiplied together to simplify. In this case, 2 * -4 = -8, so the question is asking how 8^-8 can be written.
8^-8 is the same as multiplying 8 8s together, and then finding the reciprocal (put it into a fraction where the original number is the denominator and 1 is the numerator).
Therefore, the 1 over the 8 8s multiplied together is the correct answer.
