Answer:
(b) 16^(3/2)
Step-by-step explanation:
Your calculator is a good source of information about the values of numerical expressions.
__
Here, all of the expressions have a value of 16 except 16^(3/2). That has the greatest value.
_____
<em>Additional comment</em>
Assuming you're familiar with powers of 2 and the rules of exponents, you can evaluate these without a calculator:
∛(64²) = ∛(2^6)² = (2^12)^(1/3) = 2^4
16^(3/2) = (2^4)^(3/2) = 2^6 . . . . . has the greatest value
√(16²) = ((2^4)^2)^(1/2) = 2^(4·2/2) = 2^4
∛(8^4) = ((2^3)^4)^(1/3) = 2^(3·4/3) = 2^4
__
8= 2^3; 16 = 2^4; 64 = 2^6
(a^b)^c = a^(bc)
A root is equivalent to a fractional power. The cube root is the 1/3 power, for example.
Answer:
20 ft
Step-by-step explanation:
The tree's shadow is 34/8.5 = 4 times the length of the person's shadow, so the tree is 4 times a tall as the person:
4×5 ft = 20 ft . . . . . the height of the tree
_____
Shadow lengths are proportional to the height of the object casting the shadow.
I acidently removed the stuff but anyways the answer is 12:27 or 12 to 27
do 12 + 15 = 27, and so 12 to 27 :)
