Answer:
plug in 2 for x
Step-by-step explanation:
square root of 10^2 - 2^2
square root of 96
Hello!
The first thing you should notice is that the exponent will be less than 1, as raising 27 to any power greater than 1 will make it larger, and you're trying to figure out what makes it equal to 3, a number less than 27.
Raising a number to a fractional power is taking its nth root:

is
![\sqrt[3]{21}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B21%7D%20)
, so you'll really need to take the nth root of 27 to get 3. To figure out which root, write the number in exponential form with a base of 3:

= 3

=

Now, the bases are the same (they are both 3), so you can set the exponents equal to each other:
3x = 1
Divide both sides by 3 and you've isolated x:

Answer:
The answer is A.
Step-by-step explanation:
If you pay attention, it says that the taxi had went the same speed as her car at first, and A. is the only one with the matching speeds.
Hope this helps!
Since we know that 2*2*2*2=16 and 2*17=34, we can write it out as 2*2*2*2*2*17. Since 2*2=4, we can rewrite it as 4*4*2*17=16*2*17=32*17. To get this, we can separate 17 into (10+7) and using the distributive property we get 32(10+7)=32*10+32*7=320+224=544.
The four problems can be written as 16*2*17, then 32*17, then 32*(10+7), then 320+224
