You have:\n\n2(-3^1 - 1) + 2(-3^1 - 1) + 2(-3^1 - 1) + 2(-3^1 - 1) + 2(-3^1 - 1) + 2(-3^1 - 1)\n\n3^1 = 3\n3^2 = 9\n3^3 = 27\n3^4 = 81\n3^5 = 243\n3^6 = 729\n\n2(-3 - 1) + 2(-9 - 1) + 2(-27 - 1) + 2(-81 - 1) + 2(-243 - 1) + 2(-729 - 1)\n\nOk....I assume you can add and subtract and all that stuff. You can take it from here.
