1/8 to the -3rd power
rodikova [14]
(1/8)^-3

First apply the exponent to the numerator and denominator
(1^-3/8^-3)

Then flip the fraction to get rid of negative exponents
8^3/1^3

Then evaluate exponents
512/1

Divide the numerator by the denominator
512

Final answer: 512

Find the equation of a line in slope intercept form that is perpendicular to the line y = 2x + 6 through the point (10,4)
dalvyx [7]

The equation of the straight line is y = -1/6(x - 10) + 4

<h3>How to determine the line equation?</h3>

The equation is given as:

y = 2x + 6

Linear equations are represented as:

y = mx + c

Where:

Slope = m

So, we have:

m = 6

The slopes of perpendicular lines are represented as:

n = -1/m

So, we have:

n = -1/6

The equation is then represented as:

y = n(x - x1) + y1

This gives

y = -1/6(x - 10) + 4

Hence, the equation of the straight line is y = -1/6(x - 10) + 4
