What is the value of (2/3)^-4

81/16

Step-by-step explanation:

Here the exponent is negative.  If we were to invert (2/3), we'd get:

(3/2)^4

which is significantly easier to evaluate.

3^4 = 81 and 2^4  = 16.  So the value of the given expression is    81/16.

i think is g(1)=-1.

hope that i can

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
