Simplify , using the law of exponents

option c (third one down)

Step-by-step explanation:

well its not a or d cause -10 times -3 is a positive number and then using law of exponents add the values of exponent and u get b as the only one that makes sense:)

on friday there were 15 birds

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
