For this question, it is best to first take out a factor of 2 from the equation. This will leave you with y=2(x²+2x-3). We then need to work out the two numbers that will multiply to -3 and add...

15⁰ = 1 Anything to the power of 0 is always 1. See the examples below: 10⁰ = 1; 25⁰ = 1; 50⁰ = 1.

This is an example of a question you might face during a higher maths examination. It is also a great question to test what your understanding of logarithms and powers are. I have given a quick explanatio...

This problem can be solved through substitution. The first equation provided in the question should be rearranged to give y=2x-2. This equation for y can be directly substituted into the second equation. ...

3^(3/2) = a * 3^(1/2)
3^(1/2) * 3^(-2) = 3^(3/2)Therefore a must be equal to 3^(-2)a = 1/9
