What is (-6) to the 19 exponent

If the question is -6 ¹⁹ then this really means -1*(6 ¹⁹ ) = - 6.08 x 10 ¹⁴ correct to 3 significant figures

But if you mean (-6) ¹⁹ then you need to think a little harder.

(-6) ¹ =-6

(-6) ² =36

(-6) ³ =-216

so if the power is odd the answer is negative if the power is even the answer is postitive so

(-6) ¹⁹ = - 6.08 x 10 ¹⁴ correct to 3 significant figures
