Answer:
1st, 2nd, and last.
Step-by-step explanation:
For the first two common rules can be applied such as 
= ![\frac{\sqrt[n]{a} }{\sqrt[n]{b} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5Bn%5D%7Ba%7D%20%7D%7B%5Csqrt%5Bn%5D%7Bb%7D%20%7D)
and that ![\sqrt[n]{\frac{a}{b} } = (\frac{a}{b})^{n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B%5Cfrac%7Ba%7D%7Bb%7D%20%7D%20%3D%20%28%5Cfrac%7Ba%7D%7Bb%7D%29%5E%7Bn%7D)
and for the last one this is just simplifying the radical and if you factor it you realize that, 
meaning that you can take the radical off of 5/8 and end up with that final answer
Answer:
q .no d
Step-by-step explanation:
64p^3+125
4p^3+ 5^3
(4p+ 5 ) ( 4p^2- 4p *5 + 5^2)
(4p+5) (16p- 20p+ 25)
0.4 and 0.40 are equal. That zero on the hundredths place does not matter.
Answer:
answer #4
Step-by-step explanation:
because you have 100 tiles. if you fill in 1 tile, that 1 percent. if you fill in 4 tiles, that 4 percent. you fill in 40? 40 percent. and option 2 is not a percentage so it cannot be correct
8×5×12in^2+8×5×10in^2+12×10in^2=480 in^2+400in^2+120in^2=1000in^2 if one takes all the angles
If not then the answer would be 420in^2+120in^2=540in^2
