Question

what is the solution to -19*^7sqrt15x+8=-38

Answer 1

so is the question

1. \[-19^7\times \sqrt{15x + 8} = -39\]

or

2.

\[-19 \times \sqrt[7]{15x + 8} = -38\]

Answer 2

number "2"

Answer 3

ok... divide both sides by -19

so

\[\sqrt[7]{15x + 8} = 2\]

now raise both sides to the 7th power

\[(\sqrt[7]{15x + 8})^7 = 2^7\]

so

\[15x + 8 = 128\]

now solve for x

Answer 4

8?
