(5^3 / 5^4)^-3
5^-2 / 5^-5
5(5^5 / 5^3)
5(5^5 / 5^3)
how sure are you
I apologize for the mistake in my previous response. The correct expression that is NOT equal to 125 is:
5(5^5 / 5^3)
I am certain about this correction. Thank you for pointing it out.
does all the other choices equal to 125
Let's go through each expression to check if they equal 125:
1. 5(5^3 / 2/5)^2:
= 5(125 / 0.4)^2
= 5(312.5)^2
= 5 * 312.5 * 312.5
= 488,281.25
2. (5^3 / 5^4)^-3:
= (125 / 625)^-3
= (0.2)^-3
= (5)^3
= 125
3. 5^-2 / 5^-5:
= 1 / 1/3125
= 1 / 0.00032
= 3125
Therefore, only the second expression (125) is equal to 125. The first and third expressions are not equal to 125.
