(-5⁵)²as a single power

-9765625

Step-by-step explanation: multiply the exponents first and then include the base. So, you would have 5x2=10, then se -5 to the 10th power (use a calculator).

-5^7

Step-by-step explanation:

as you have -5 to the power of 5 and u need to square that u have to add the powers therefore making it -5 to the power of

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
