Answer:

Mostly correct

For Q3, you are doing great, you remembered that negative numbers can happen if the exponent is an odd number.

For Q4, I think you were confused with the fractions,

4(i)

(\frac{2}{3} )^{4} = (\frac{2^{4}}{3^{4}}) = (\frac{16}{81}) =0.198

4(ii) is also wrong but I'll let you try to fix it yourself following what I given you for 4(i). You should get 1/64

Hope this helps!

Make b the subject of the formula P=2a+b
Gelneren [198K]
In order to make b the subject of this equation, we must isolate it on the left side. We can do this by following these steps:

P = 2a+b

Subtract b from both sides

P - b = 2a+b-b

P-b=2a

Subtract P from both sides

P-b-P=2a-P

-b=2a-P

Now, we have isolated b, but it is negative. We can fix this by multiplying both sides of the equation by -1.

-(-b)=-(2a-P)

b=-2a+P

Which is your final answer.
b = -2a+P.
Hope that helped! =)
