Answer:
B. 4
Step-by-step explanation:
Given :
The logarithm function can be converted to an exponential function as
![[\log_ab=c]](https://tex.z-dn.net/?f=%5B%5Clog_ab%3Dc%5D)
can be expressed as ![[a^c=b]](https://tex.z-dn.net/?f=%5Ba%5Ec%3Db%5D)
Similarly for the given expression
We can write,
Using property of negative exponents ![[a^{-b}=\frac{1}{a^b}]](https://tex.z-dn.net/?f=%5Ba%5E%7B-b%7D%3D%5Cfrac%7B1%7D%7Ba%5Eb%7D%5D)
So we can write that as:
Writing the exponents in radical form as ![a^{\frac{b}{c}}=(\sqrt[c]{a})^b](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bb%7D%7Bc%7D%7D%3D%28%5Csqrt%5Bc%5D%7Ba%7D%29%5Eb)
Taking cube root both sides to remove the cube.
![\sqrt[3]{(\sqrt{x})^3}=\sqrt[3]{8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%28%5Csqrt%7Bx%7D%29%5E3%7D%3D%5Csqrt%5B3%5D%7B8%7D)
Squaring both sides to remove square root.
∴ 
Answer:
D. 8.8
Step-by-step explanation:
As the pythagorean theorem.
A² + B² = C²,
5.4 × 5.4 + 7 × 7 = C²,
29.16 + 49 = C²,
78.16 = C²,
8.8 ≈ C
Answer:
358
Step-by-step explanation:
Oof, division rule:
(f/g)'=(f'g-fg')/g^2
Let (9t-8)^6=f and t+2=g
Thus we get
(9*6(9t-8)^5*(x+2)-(9t-8)^6)/(x+2)^2
(54(9t-8)^5*(x+2)-(9t-8)^6)/(x^2+4x+4)
I'm not sure how much I'm supposed to simplify this...
Answer:
2
Step-by-step explanation:
We have y=x²-2x+2
Plug in 0 for x
y= 0²-2(0)+2
y=2
Hope this helps
