The correct sentence is: Ojalá que no llueva este fin de semana. 1) you need to use the subjunctive conjugation of the verb llover because you are expresses a desire 2) it is este not esta because it is el fin not la fin.

Using pythagorean theorem, we can find the hypotenuse. a^2 + b^2 = c^2 3^2 + 4^2 = c^2 9 + 16 = c^2 25 = c^2 c = 5 Therefore the hypotenuse is 5cm long.

When you have the same base in a exponent multiplication, the exponents are simply added! Hence, it can be simplified to 4^8.
