Tom simplified an expression in three steps, as shown below: Step 1 Step 2 Step 3
x?y8
= x
yx4
x®y2
,6,16
x?y8
-14 y²
Which is the first incorrect step and why?
Step 1: all the exponents are increased by 4
Step 2: the exponents of the same base are added during multiplication
о
Step 3: the exponents of the same base are subtracted during division
Step 3: all the exponents are added during division

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
