4x^2 - 36 = 0
4x^2 = 36
x^2 = 9
x = 3 or -3
the answer is C
Answer:
19. 1 do 4^5 which is 1024 then do 1024^0 which is 1
21. 0.000064 do 5^-2 which is 0.04 then do 0.04^3 which is 0.000064
23. 2.33 do 9^4 which is 6561 then do 6561^-2 which is 2.32305731 so you round it to 2.33
btw you should talk to me more
4^0 is 1 because any number to the zero power is one so 1*5=5
4,408,730 = 4,000,000 + 400,000 + <span>8,000 + 700 + 30 </span>
