Question

Solve Algebraically 2^3-x=565

Answer 1

x = -557

Explanation:

2^3 is 2x2x2 which equals 8. 8 - x = 565. Move the constant to the right-hand side and change its sign. -x = 565 - 8. This is 557. Now change the negative sign on the x to a positive and the positive sign on the 557 to a negative. x= -557.

Answer 2

x = 3 − log 565/ log 2 = − 6.142107057

Explanation:

2^3-x =565

Log 2^3-x = log 565

(3-x) times log 2 = log 565

3 − x = log 565 / log 2

3 − log 565 / log 2 = x

x = 3 − log 565/ log 2 = − 6.142107057
