First write out your original equation.

Then use the law of exponents(power of a power) to simplify.

(Multiply the numerator and denominator exponents by the outside power.)
The answer is 4 to the 21st over 5 to the 6th.
Point slope formula: y-y1=m(x-x1). Answer: y-7=6(x-(-4))
Answer:
175.929188601
Step-by-step explanation:
Subtract these 2 equations,
5x-5x +3y-y = -4-6
2y = -10
y = -5
-5 is your answer.
