Answer:
x = 21
Step-by-step explanation:
(3x+1) ^1/3=4 means that the 1/3 is an exponent that can be rewritten as a cube root.
You can bring the cube root to the other side of the equation.
1. I chose to bring it to the other side of the equation, making it a cube.
(3x+1) ^1/3 = 4
(3x+1) = 4^3
(3x+1) = 4 * 4 * 4
(3x+1) - 1 = 64 - 1
3x/3 = 63/3
x = 21
.12×10^5
... i got this by taking the first number 8 and then counting the places behind the 8 which would be 5 so than you move the decimal place by 5 so you get 8.12 then you show theirs 5 places behind the 8 by adding the 10^5 so you get 8.12×105
Yes because the opposite of addition is multiplication, because they are both adding anyways, so that’s how they are opposite of eachother. And 8 takes the place of H.
