Question

Anyone who knows how to solve this?

Answer 1

x = -2, 5

Explanation:

if the given expression is true then powers on both sides should be equal

then x^2 = 3x + 10

x^2 -3x - 10 = 0

x^2 -5x + 2x -10 = 0

x (x + 2) - 5 (x + 2) = 0

(x + 2) (x - 5) = 0

x = -2, 5

Answer 2

Set an equation with the exponents equal to each other because g raised to some exponent is only equal to g raised to the same exponent
