1 5^{- 3 y} = 9

y = - \frac{2 ln ( 3 )}{3 ln ( 15 )}

Decimal Notation

y = - 0.27045 \dots

Solution steps

1 5^{- 3 y} = 9

Apply exponent rules

- 3 y ln (15) = ln (9)

Solve

- 3 y ln (15) = ln (9) : y = - \frac{2 ln ( 3 )}{3 ln ( 15 )}

y = - \frac{2 ln ( 3 )}{3 ln ( 15 )}

y, z = x e^{x^{2} y}

lo g_{10} (10 0^{x}) = 70

(- 7)^{x - 2} = 16.807

(3^{2})^{5} = 24 3^{x}

d, c = ba + a^{d}
