Multiply the terms with the same base by adding their exponents

- 4^{2 + 1} x

Add the numbers

- 4^{3} x

- 4^{3} x - 4

Solution

- 64 x - 4

Show Solution

- 4 (16 x + 1)

Evaluate

- 4^{2} \times 4 x - 4

Multiply

More Steps

Evaluate

4^{2} \times 4 x

Multiply the terms with the same base by adding their exponents

4^{2 + 1} x

Add the numbers

4^{3} x

- 4^{3} x - 4

Solution

- 4 (16 x + 1)

Show Solution

x = - \frac{1}{16}

Alternative Form

x = - 0.0625

Evaluate

- 4^{2} \times 4 x - 4

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

- 4^{2} \times 4 x - 4 = 0

More Steps

Multiply the terms

4^{2} \times 4 x

Multiply the terms with the same base by adding their exponents

4^{2 + 1} x

Add the numbers

4^{3} x

- 4^{3} x - 4 = 0

Evaluate the power

- 64 x - 4 = 0

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

- 64 x = 0 + 4

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

- 64 x = 4

Change the signs on both sides of the equation

64 x = - 4

Divide both sides

\frac{64 x}{64} = \frac{- 4}{64}

Divide the numbers

x = \frac{- 4}{64}

Solution

More Steps

Evaluate

\frac{- 4}{64}

Cancel out the common factor 4

\frac{- 1}{16}

Use \frac{- a}{b} = \frac{a}{- b} = - \frac{a}{b} to rewrite the fraction

- \frac{1}{16}

x = - \frac{1}{16}

Alternative Form

x = - 0.0625
