### Subject: Spanish

Find the error in the sentence below: Ojalá que no llueve esta fin de semana.

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.

### Subject: Trigonometry

In a right angled triangle, the longest side is unknown. We know that the sides that make up the right angle are 3cm and 4cm. How long is the longest side?

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.

### Subject: Pre-Algebra

Using exponent laws, how can the following be simplified: 4^3 x 4^5

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