Question

find the value of x such that (-11)raise to x+2 ×(-11)raise to 5 =(-11) raise to-4​

Answer 1

Answer:

The answer will be -13.

Step-by-step explanation:

(-11)^(x+2) × (-11)^5 =(-11)^(-4);

(-11)^(x+2+5) =(-11)^(-4);

(-11)^(x+7) =(-11)^(-4);

Here, bases are same.

Thus, x+7 = -4

x = -13;

That's all.
