Answer:

$\sqrt[5]{25x^{2}y^{4}z^{6} }$

Step-by-step explanation:

going to the 2/5 power is the the fifth root of a square. For fraction exponents going into radical form use the denominator as you root of and use the numerator as the exponent of the rest making sure to multiply any other exponents by that number and when there is no exponent treat it as having an exponent of one for the multiplying.

solution

Find the equivalent ratio for 64%. Write your answer in simplest form.

For this case we can do the following:

64% = 64/100

And if we simplify we got:

64/100 = 32/50 = 16/25 = 0.64

Find the value of y in the equation attached to this question

dlinn [17]

Answer:

y = 4

Step-by-step explanation:

1) Simplify $3^5$ to 243.

${9}^{y}=\frac{243\times {9}^{6}}{{27}^{3}}$

2) Simplify ${9}^{6}$ to 531441.

${9}^{y}=\frac{243\times 531441}{{27}^{3}}$

3) Simplify $243\times 531441$ to 129140163.

${9}^{y}=\frac{129140163}{{27}^{3}}$

4) Simplify ${27}^{3}$ to 19683.

${9}^{y}=\frac{129140163}{19683}$

5) Simplify $\frac{129140163}{19683}$ to 6561.

${9}^{y}=6561$

6) Convert both sides to the same base.

$9^y=9^4$

7) Cancel the base of 9 on both sides.

$y=4$
