Solve (a^2 a 1) ( a^2 a^2)-12

Evaluate

(a^{2} \times a \times 1) (a^{2} \times a^{2}) - 12

To find the roots of the expression,set the expression equal to 0

(a^{2} \times a \times 1) (a^{2} \times a^{2}) - 12 = 0

Multiply the terms

More Steps

a^{3} (a^{2} \times a^{2}) - 12 = 0

Multiply the terms

More Steps

a^{3} \times a^{4} - 12 = 0

Multiply the terms

More Steps

a^{7} - 12 = 0

Move the constant to the right-hand side and change its sign

a^{7} = 0 + 12

Removing 0 doesn't change the value,so remove it from the expression

a^{7} = 12

Take the 7 -th root on both sides of the equation

7 a^{7} = 712

Solution

a = 712

Alternative Form

a \approx 1.426162
