10 sorry i cant do exponents :p
Do you have a formula sheet or was one provided to you

10 squared is 100
Do the 5+3 next to get 8 then square the 8 to get 64
That leaves you with 100+64-5=159
Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that
We have the a² and the b² in the equation 
, and we <em>almost </em>have a 2ab in the equation 
. To get that 2ab, we can simply double both sides of the first equation to get 
. From there, we'll add the first two equations together, giving us the summed equation
And since , we can equivalently say that
