Solve m^21399-1 - ScanMath

Question

Simplify the expression

1399 m^{2} - 1

Evaluate

m^{2} \times 1399 - 1

Solution

1399 m^{2} - 1

Show Solution

m_{1} = - \frac{1399}{1399}, m_{2} = \frac{1399}{1399}

Alternative Form

m_{1} \approx - 0.026736, m_{2} \approx 0.026736

Evaluate

m^{2} \times 1399 - 1

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

m^{2} \times 1399 - 1 = 0

Use the commutative property to reorder the terms

1399 m^{2} - 1 = 0

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

1399 m^{2} = 0 + 1

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

1399 m^{2} = 1

Divide both sides

\frac{1399 m ^{2}}{1399} = \frac{1}{1399}

Divide the numbers

m^{2} = \frac{1}{1399}

Take the root of both sides of the equation and remember to use both positive and negative roots

m = \pm \frac{1}{1399}

To take a root of a fraction,take the root of the numerator and denominator separately

\frac{1}{1399}

Simplify the radical expression

\frac{1}{1399}

Multiply by the Conjugate

\frac{1399}{1399 \times 1399}

When a square root of an expression is multiplied by itself,the result is that expression

\frac{1399}{1399}

m = \pm \frac{1399}{1399}

Separate the equation into 2 possible cases

m = \frac{1399}{1399} m = - \frac{1399}{1399}

Solution

m_{1} = - \frac{1399}{1399}, m_{2} = \frac{1399}{1399}

Alternative Form

m_{1} \approx - 0.026736, m_{2} \approx 0.026736
