Answer:
x=16°
y=25°
Step-by-step explanation:
7x=112
x=112/7
x=16
90+y=115
y=115-90
y=25
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.
Answer:
{-4 = 7, 5 = 5} = {False, True}
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Standard form is written according to the highest exponent on the variable to the lowest. This expression has exponents that descend from 8 to 7 and to 1. B is the correct solution.
