The given expression is

49 is the square of 7 and 64 is the square of 8.
So we can write the given expression as


Answer:

Step-by-step explanation:
Which expression represents [⁵√(−21)]⁶ in rational exponent form?
Solution:
Rational numbers are numbers which can be expressed as fractions in the form a / b, where a, b are integers and b is not equal to zero.
A rational exponent is an exponent that is a fraction. For example √2 =
.
When expressing a number in rational exponent form, the numerator of the fractional exponent refers to a normal power, but the denominator refers to the root.
![[\sqrt[5]{(-21)}]^6 = (-21)^\frac{6}{5}](https://tex.z-dn.net/?f=%5B%5Csqrt%5B5%5D%7B%28-21%29%7D%5D%5E6%20%20%3D%20%28-21%29%5E%5Cfrac%7B6%7D%7B5%7D)
Answer:
y = -0.83x - 2
Step-by-step explanation:
Slope intercept form is y = mx+b.
M is the slope: In this case the slope (rise/run) is 10/12. However, the slope is decreasing is that would make it negative.
Now we have: y = -0.83x + b
B represents the y-intercept. The y-intercept here is -2. So our final equation is:
y = -0.83x - 2
