Step 2.1

Subtract $2$ from both sides of the equation.

$m^{3} = 87 - 2$

Step 2.2

Subtract $2$ from $87$ .

$m^{3} = 85$

Step 3

Take the specified 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:

$m = 4.39682967 \dots$
