Answer: Exponents are like the multiplication of a number against itself that many times.
Step-by-step explanation: 2^4=2x2x2x2
3^3=3x3x3
Ha! 3 equations of 3 unknown ... :-)Let's see if I still remember ...Sorry, it will take a little bit (English is not my language ...)
Answer: choice B, 40.5 degrees
The triangle is isosceles based on the fact that AC = BC (the tick marks are the same). The angles opposite the congruent sides are also congruent
angle A = angle B = x for some unknown number x
The three angles A,B,C add to 180, so,
A+B+C = 180
x+x+99 = 180
2x+99 = 180
2x = 180-99
2x = 81
x = 81/2
x = 40.5
So angle A and angle B are both 40.5 degrees
Check:
A+B+C = 180
40.5+40.5+99 = 180
180 = 180 answer is confirmed
==============================
Edit
The sides with the two tick marks are the same length, so 7x-4 is the same as length as 31
7x-4 = 31
7x = 31+4
7x = 35
x = 35/7
x = 5
Answer is choice B) 5
Answer:
![24\sqrt[3]{x^{7}}](https://tex.z-dn.net/?f=24%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%7D)
Step-by-step explanation:
The exponent rule that applies to products like this is ...
... (a^b)(a^c) = a^(b+c)
In your problem, this is
... x^(1/3)·x^2 = x^(1/3 +2) = x^(1/3 +6/3) = x^(7/3)
This fractional exponent translates to the root of a power:
... = (x^7)^(1/3)
In typeset form, it is ...
![\sqrt[3]{x^{7}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%7D)
You have already figured correctly that the coefficient is 3·8 = 24.
