Question

Simplify the expression

92 d^{7} - 1

Evaluate

d \times d^{6} \times 92 - 1

Solution

More Steps

Evaluate

d \times d^{6} \times 92

Multiply the terms with the same base by adding their exponents

d^{1 + 6} \times 92

Add the numbers

d^{7} \times 92

Use the commutative property to reorder the terms

92 d^{7}

92 d^{7} - 1

Show Solution

d = \frac{7 9 2 ^{6}}{92}

Alternative Form

d \approx 0.524154

Evaluate

d \times d^{6} \times 92 - 1

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

d \times d^{6} \times 92 - 1 = 0

Multiply

More Steps

Multiply the terms

d \times d^{6} \times 92

Multiply the terms with the same base by adding their exponents

d^{1 + 6} \times 92

Add the numbers

d^{7} \times 92

Use the commutative property to reorder the terms

92 d^{7}

92 d^{7} - 1 = 0

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

92 d^{7} = 0 + 1

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

92 d^{7} = 1

Divide both sides

\frac{92 d ^{7}}{92} = \frac{1}{92}

Divide the numbers

d^{7} = \frac{1}{92}

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

7 d^{7} = 7 \frac{1}{92}

Calculate

d = 7 \frac{1}{92}

Solution

More Steps

Evaluate

7 \frac{1}{92}

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

\frac{7 1}{7 92}

Simplify the radical expression

\frac{1}{7 92}

Multiply by the Conjugate

\frac{7 9 2 ^{6}}{7 92 \times 7 9 2 ^{6}}

Multiply the numbers

Evaluate

792 \times 7 9 2^{6}

The product of roots with the same index is equal to the root of the product

7 92 \times 9 2^{6}

Calculate the product

7 9 2^{7}

Reduce the index of the radical and exponent with 7
