if your book scales 10 times then each surface will scale 10^2=100 times. so the total surface would be 100*126.25=12625

Select True or False for each statement.

SSSSS [86.1K]

$\left( \dfrac 1 {64} \right)^{- 5/6} =64^{5/6} = (\sqrt[6]{64})^5 = 2^5 =32$

TRUE

$\sqrt[5]{36^4}=36^{4/5}$

which surely isn't 36. FALSE

$\sqrt{12} - \dfrac 2 5 \sqrt{75} = 2 \sqrt{3} -\dfrac 2 5 (5) \sqrt{3} = 0$

FALSE

For the fourth one we have a

$\sqrt{98b} + \sqrt{2b}$

which isnt

$10\sqrt{b}$

so this is FALSE.

$\dfrac{1}{(\sqrt 5 - \sqrt 6)^2}$

$= \dfrac{1}{(\sqrt 5 - \sqrt 6)^2} \cdot \dfrac{(\sqrt 5 + \sqrt 6)^2}{(\sqrt 5 + \sqrt 6)^2}$

$= \dfrac{(\sqrt 5 + \sqrt 6)^2}{ ( (\sqrt 5 - \sqrt 6)(\sqrt 5 + \sqrt 6))^2}$

$= \dfrac{(\sqrt 5 + \sqrt 6)^2}{( 5-6)^2}$

$=(\sqrt 5 + \sqrt 6)^2$

No fractions in that one so FALSE.

Cammie goes to the gym to exercise 4 times per week. Altogether how many times does she go to the gym in 10 weeks?

Tamiku [17]

The answer is 40 because if you multiply 4 times per week× for 10 weeks=40 times for ten weeks.

Evaluate 0.53n when n=3 and when n=-3

ratelena [41]

What you have to do here, is replace n with 3 and multiply 0.53(3) and you will get your first answer. Do the same thing with -3: multiply 0.53(-3) and you will have your second answer. If you do this, I do believe your question will be answered.
