Solve 5x^5-5+5:5 - ScanMath

Question

Simplify the expression

5 x^{5} - 4

Evaluate

5 x^{5} - 5 + 5 \div 5

Divide the terms

5 x^{5} - 5 + 1

Solution

5 x^{5} - 4

Show Solution

x = \frac{5 2500}{5}

Alternative Form

x \approx 0.956352

Evaluate

5 x^{5} - 5 + 5 \div 5

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

5 x^{5} - 5 + 5 \div 5 = 0

Divide the numbers

5 x^{5} - 5 + 1 = 0

Add the numbers

5 x^{5} - 4 = 0

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

5 x^{5} = 0 + 4

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

5 x^{5} = 4

Divide both sides

\frac{5 x ^{5}}{5} = \frac{4}{5}

Divide the numbers

x^{5} = \frac{4}{5}

Take the 5 -th root on both sides of the equation

5 x^{5} = 5 \frac{4}{5}

Calculate

x = 5 \frac{4}{5}
