It's an expression which <span>shows that two quantities are not equal.</span>
1. Anything raised to zero is 1.
There are a few ways you could go about this. One way is to use sin 60 to calculate the value of a. In other words, sin 60 = a / 8sqrt(3). Simplifying that you should get a = 12.
So F should be the right answer.
Cheers and good luck
5. do 0.7÷0.05. it gives you 14. to check your work, do 14×0.05 which will be 0.7
