Hey, 1. If 0<r<1 then; r-1 is negative r^n1 is also negative as for 0<r<1, r^n<r This means t is positive 2. If r<-1 r-1 will be negative r^n-1 can be positive or negative depending on n (even or odd) This means t can either be negative or positive Thus conclusively nothing can be said about t's sig...

Simply break down the 10=2*5 on the right hand side; You'll get the power of 1/5 as 35 on the Right side Oh the left side the power of 1/5 is m As both should be equal m=35 The use of reciprocals can make the question confusing, if you are not comfortable with reciprocals, you can write: (1/5)^m as ...

Heres a simple solution;
Let a^2+b^2=x adding this with a^2-b^2=30 we get
2a^2=30+x
a=(30+x/2)^0.5
b=(x-30/2)^0.5
substituting these in ab=10
and squaring both sides
(x+30)(x-30)=4*100
x^2-900=400
x=a^2+b^2=(1300)^0.5 = 36.055
Hope that helps!
