You would take 2 and replace it for x in your other equation and solve.
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.

11 cubed equals 1331

250(x) = 400,000 Use logs to base '10' Hence log250^(x) = log400,000 xlog250 = log 400,000 Notirce how the power (x) becomes the coefficient. This is oerfectly correct under 'log' rules. x = log 400,000 / log 250 (NOT log(250/400,000). x = 5.60206 / 2.39794 x = 2.33619689..... ~ 2.33619 to 5 d.p.

No, it would be rounded to 400000.
3 to the power of 3 is the same as 3 cubed. To put it in an equation that would be 3x3x3 which equals 27.

You would do it it by oppisites. 3+2+4=9 which equals C.

"N cubed" refers to the mathematical operation of raising a number to the power of 3. This means multiplying the number by itself three times. For example, if n = 2, then n cubed would be 2 x 2 x 2, which equals 8. In general, n cubed can be represented as n^3 in mathematical notation.
