The answer & explanation for this question is given in the attachment below.
(-6.8)^2
The product of a squared negative number is ALWAYS positive.
So (-6.8)^2 = 46.24
√(-196) Is impossible.
What's under the radical MUST ALWAYS be positive. The square root of a negative number doesn't exist, so is impossible to calculate.
Hope this Helps! :)
Answer:
-10.49.
Step-by-step explanation:
Using order of operations PEMDAS:
4(-8+4.5)/ 6.25 + (-8.25)
= 4 * -3.5 / 6.25 - 8.25
= -14/6.25 - 8.25
= -2.24 - 8.25
= -10.49.
Answer: -0.7
Step-by-step explanation:
1. 23.5 x 2.3 = 54.05
when you are multiplying decimals you have to line up the decimal point.
example:
23.5
2.3
2. 12.34 x 4.321 = 53.32114
once again you need to line up your decimals when multiplying two decimals.
example: however I had to add a zero to the number 12.34 so everything would line up correctly. I hope you understand that.
12.340
4.321
