Question

If (5/16)^17* (5/16)^5=(5/16)^x and (6/19)^8*(6/19)^4=(6/19)^y,then (x+y)^3

Answer 1

Step-by-step explanation:

(5/16)¹⁷ x (5/16)⁵ = (5/16)²².

x=22

(6/19)⁸ x (6/19)⁴ = (6/19)¹²

y=12

(x+y)³

(22+12)³

(34)³

34*34*34

39304

Answer 2

Solution:

(x+y)³=34³=27744

Step-by-step explanation:

(5/16)¹⁷×(5/16)⁵=(5/16)¹⁷+⁵ (a^m×a^n=a^m+n)

=(5/16)²²

(6/19)⁸×(6/19)⁴=(6/19)⁸+⁴ (a^m×a^n=a^m+n)

=(6/19)12

x=22, y=12

(x+y)³=(22+12)³

=34³

=27744
