x≥4.5
x is all number greater than or equal to 4.5
Step-by-step explanation:
2x≥5+4
2x≥9
x≥9/2
x≥4.5
x is all number greater than or equal to 4.5
<u>Given</u><u> info</u><u>:</u><u>-</u><u> </u>What number should [(-5/3)³]^-3 be multiply obtain (-3/5)⁴ ?
<u>Explanation</u><u>:</u><u>-</u>
Given number = [(-5/3)³]^-3
Let the required number be X
On multiplying [(-5/3)³]^-3 with X
⇛ [(-5/3)³]^-3 × X
According to the given problem
The result = (-3/5)⁴
⇛ [(-5/3)³]^-3 × X = (-3/5)⁴
⇛ (-5/3)^(3×-3) × X = (-3/5)⁴
Since (a^m)^n = a^mn
⇛ (-5/3)^-9 ×X = (-3/5)⁴
⇛(-3/5)⁹ ×X = (-3/5)⁴
Since a^-n = 1/a^n
⇛X = (-3/5)⁴/(-3/5)⁹
⇛X = (-3/5)^(4-9)
Since a^m / a^n = a^(m-n)
⇛ X = (-3/5)^-5
⇛ X = (-5/3)⁵
Since a^-n = 1/a^n
Therefore, X = (-5/3)⁵
<u>The required number for the given problem is (-5/3)</u><u>⁵</u><u>.</u>
4 · x^4 · x^4 · y
4 x^8 y
In words: four times x to the eighth times y
Answer:
A. Yes
B. Yes
C. No
Step-by-step explanation:
We can substitute each value in to the equation and see if the sides match up. Let's start with a.
So, n = 2 works for equation a. Let's try B.
So, m = 
works for B. Now let's try C.
So y = 30 doesn't work for C.
Hope this helped!
Answer:C
Step-by-step explanation:
(a-5)*(a+3）
a*a+a*3+(-5)*a+(-5)*3
