@PhysInHistory And yet, as explained in the link below, the primary effect of the warming of the Earth has been increased greening of the Earth (that is, increased plant growth):

I love you, dad. I’m endlessly grateful for the good fortune of being your daughter. The gentle yet powerful steadfast unconditional love you have shown to us throughout our lives is unmatched. When I think back over my life, through thick and thin, you have been by my side every step of the way (often with a guitar or a tennis racquet in hand), not only as my dad but my best friend. I love you with all my heart ❤️ and wish I could be there to spoil you today for Fathers Day!

@H0H0v Multiplying the eq by 40 gives:
36 +18 H = 25H -20
Solving for H gives:
H=8 (ans)

[Jean C. Piquette @realjpiquette]

@IQTestBrain 90-36 = 54 (ans)

[Jean C. Piquette @realjpiquette]

@mathtech789 Equation is equivalent to:
Sqrt[x^(3/2)] = 5 Sqrt[5]
Squaring gives:
x^(3/2) = 125
Taking the cube root of both sides gives:
x^(1/2) = 5
Squaring both sides gives:
x=25 (ans)

@MehrdadBasiry Sqrt[121] = 11
Ans: c

@MathMath901 x = Log[3]/Log[2]
y= Log[5]/Log[3]
z =Log[8]/Log[5]

x y z = Log[8]/Log[2]
x y z = 3 Log[2]/Log[2]
x y z = 3

Ans: B

@mathsrick_ Rewriting eq as:
x^4 - x^2 = 0,
then factoring gives:
x^2 (x+1) (x-1)=0

Roots: x=0,-1,+1.

x=0 is a repeated root, so all 4 solutions to this 4th-degree polynomial are:
x=0,0,-1,+1.
