The 4th one because when you divide 270 by 15 you get 18 and when you also divide 135 by 7.5 you get 18 when something is proportional you get the same answer
Answer:
Step-by-step explanation:
when you have the same base and its times you can add the exponents
a² + a³ + a have exponents of 2+ 3 + 1 = 6
so its
Answer:
a^(1/4) * b^(1/4)
Step-by-step explanation:
(a^ 1/2 * b^ 1/2) ^1/2
We know that we can separate the terms
a^1/2 ^1/2 * b^1/2 ^1/2
We also know that a^b^c = a^(b*c)
a^(1/2 *1/2) * b^(1/2 *1/2)
a^(1/4) * b^(1/4)
84 and to check 84 x 52 = 4368
