1) find x
y=1/(x+3) -4
y+4=1/(x+3) -4+4
y+4=1/(x+3)

x+3 =1/(y+4)
x= 1/(y+4) - 3

2) change x on y , and y on x

x= 1/(y+4) - 3
y= 1/(x+4) - 3 This is an answer.

Answer:

D.f=288.68

Step-by-step explanation:

f+ 523.89 = 812.57

subtract 523.89 from both sides

f+ 523.89-523.89 = 812.57-523.89

Nuetrik [128]

Answer:

4²¹/5⁶ or 4398046511104/15625

Step-by-step explanation:

Remember, when raising a term with an exponent to some power, you must multiply the powers.

$(\frac{4^{7} }{5^{2} })^{3} \\\\ = (\frac{(4^{7})^{3} }{(5^{2})^{3} }) \\\\= \frac{4^{7 * 3} }{5^{2* 3} } \\\\= \frac{4^{21} }{5^{6} } \\\\=\frac{4398046511104}{15625}$
