<h3>I'll teach you how to solve (81x^-20 y^-16)^-3/4</h3>
---------------------------------------------------------------
(81x^-20 y^-16)^-3/4
Apply exponents rule:
(81x^-20 y^-16)^-3/4=
1 / (81x^-20 y^-16)^-3/4
Simplify (81x^-20 y^-16)^-3/4:
1/27/x^15 y^12
Apply the fraction rule:
x^15 y^12 / 27
Your Answer Is x^15 y^12 / 27
plz mark me as brainliest if this helped :)
140 because 2 is below 5 so its 140
Maximum number of packs of 10 = 30 / 10 = 3 packs
Therefore, the different ways to but them are as follows:
3 packs of 10 and zero single pieces (30-3(10)=0)
2 packs of 10 and 10 single pieces (30-2(10)=10)
1 pack of 10 and 20 single pieces (30-1(10)=20)
zero packs of 10 and 30 single pieces (30-0(10)=30)
A and C could be the answer
