Solve 08=1/2*a*81^2

$$08 = 1 / 2 \times a \times 81 ^ { 2 }$$

Solve for a

$$a=0$$

Steps for Solving Linear Equation

Multiply 0 and 8 to get 0.

$$0=\frac{1}{2}a\times 81^{2}$$

Calculate 81 to the power of 2 and get 6561.

$$0=\frac{1}{2}a\times 6561$$

Multiply \frac{1}{2} and 6561 to get \frac{6561}{2}.

$$0=\frac{6561}{2}a$$

Swap sides so that all variable terms are on the left hand side.

$$\frac{6561}{2}a=0$$

Product of two numbers is equal to 0 if at least one of them is 0. Since \frac{6561}{2} is not equal to 0, a must be equal to 0.

$$a=0$$
