Answer:
a) 11
b) 9
Step-by-step explanation:
a) x=4 y=3
2x+y
2(4)+(3)
8+3
=11
b) a=-2 b=5
a^2+b
(-2)^2+(5)
4+5
=9
90^6=531441000000
80^-4= 1/80^4= 1/4960000
For this, use negative power rule x^-a= 1/x^a

Answer:
g = 
Step-by-step explanation:
Given
2(g - h) = b + 4 ← distribute parenthesis on left side
2g - 2h = b + 4 ( add 2h to both sides )
2g = b + 4 + 2h ( divide both sides by 2 )
g =
