Solve for m 87=2+m^3

$87 = 2 + m^{3}$

Step 1

Rewrite the equation as $2 + m^{3} = 87$ .

$2 + m^{3} = 87$

Step 2

Move all terms not containing $m$ to the right side of the equation.

Subtract $2$ from both sides of the equation.

$m^{3} = 87 - 2$

Subtract $2$ from $87$ .

$m^{3} = 85$

Step 3

Take the cube root of both sides of the equation to eliminate the exponent on the left side.

$m = \sqrt[3]{85}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$m = \sqrt[3]{85}$

Decimal Form:

$m = 4.39682967 \dots$
