Dimas [21]
The answer is 5. Work backwards: first add 7 to 9, then divide by 2, then subtract 3.

Cross Check:
5+3=8
8*2=16

HELP PLEASE!!!!!!! Asap Giving out brainliest!<br> Which of the following has the greatest value?
Jlenok [28]
1/3^-2

You flip the denominator and the numerator to make the 3^-2 positive. 

3^2/1= 3^2= 9 

1/2^-3 

2^3/1= 2^3= 8 

I can already tell you that the negative exponents are not going to be as high in value. 

3^-2= 1/3^2= 1/9
2^-3= 1/2^3= 1/8

1/3^-2 (the first option) <=== the highest in value

I hope this helps!

What is the square root of -1?
Alchen [17]

Answer: √−1=i.

Step-by-step explanation: When we say that the square root of a negative number "doesn't exist", we mean that there is no real number solution. However, if we consider complex numbers, we then get a solution to √−1=i.
