Answer 6

b. is irrational

Answer 7

ok for part a, do u know that when u have a fraction as an exponent, it means take the base to the nth root? where n is the denominator in the fraction.

Answer 8

does that help

Answer 9

not really

Answer 10

can you just solve the problems with showing the steps please

Answer 11

can you solve it @shyamani9

Answer 12

um. ok. Its more of explaining why something happens but ill try

Answer 13

or you could just give me the answer i wont mind

Answer 14

@oleg3321 we know that \[64^{1} = 64\]
so \[64^{1/2} = \sqrt{64^{1}}\]

Answer 15

Look at Rational Exponents section under this awesome Hotmath guide.
http://hotmath.com/hotmath_help/topics/properties-of-exponents.html

Answer 16

\[64^{1/2}= (8^{2})^{1/2}=8\], which is the sqrt of 64.
Area = length*width so 7*7sqrt7: which is an irrational number

Answer 17

@study100 is that part one only

Answer 18

the are would be 7*sqrt7

Answer 19

ok so for a. The answer is the square root of 64 because there is a property of exponent that states that when you have a fraction as an exponent, the answer is the base to the nth root, where n is the denominator of the fraction

Answer 20

the diagrams work, but it asks you to explain

Answer 21

part b is
Area = length x width.
Now what do you get for area @oleg3321

Answer 22

idk

Answer 23

for the second part, the answer is irrational because \[7\sqrt{7}\]

Answer 24

is irrational

Answer 25

yes square root of 7 cannot turn in fractions, therefore they are irrational.
