The correct answer is 0.8
⁴√400 / ⁴√5 = 400^¼ / 5^¼
= (5 x 2²)² / 5^¼
= 5² x 2⁴ / 5^¼
= ⁴√5^7 x 2⁴
Answer:
x = 3√7
Step-by-step explanation:
From the right triangle given in the picture,
Altitude or height of the triangle (AD) = x
Base or hypotenuse of the given triangle (BC) = 16
Length of segment BD = 16 - 7 = 9
By using geometric mean theorem in the given triangle,
![\frac{AD}{BD}=\frac{DC}{AD}](https://tex.z-dn.net/?f=%5Cfrac%7BAD%7D%7BBD%7D%3D%5Cfrac%7BDC%7D%7BAD%7D)
(AD)² = (BD)(CD)
x² = 9×7
x = √63
x = 3√7
The correct answer is 4 ( 6x - 1 )
5^0=1
Any exponent to zero power equals 1
