<span>Rational exponent are exponents written in the form of a fraction.
A rational power can be rewritten as a radical in the following way: the bottom of the rational exponent is the root, while the top of the rational exponent is the new exponent on the radical.
Example: X^(1/2)= </span>√X
Step-by-step explanation:
= -4 ÷ ( 1/3 × (7 - 1/2) ) + 3
= -4 ÷ ( 1/3 × 13/2 ) + 3
= -4 ÷ 13/6 + 3
= -4 × 6/13 + 3
= -24/13 + 3
= -24/13 + 39/13
= 15/13
Answer:
4x -2 = 3 and 4x + -2 = 3
Step-by-step explanation:
-2 + 4x = 3 ---- 4x -2 = 3 ------------ 4x + -2 = 3
+2 +2 - 2 +2
------------------ ----------------
4x = 5 4x = 5
---- ---- ----- -----

x = 1.25 or 1 1/4 x = 1.25 or 1 1/4
(180 miles=7.5 hours, 20 miles=2.5/3=0.8333) 7.5+0.8333=8.3333 or 8h and 20 minutes.
