It looks like they're multiplied, then you can simply add the exponents,
b⁸ * b⁴ = b⁸⁺⁴ = b¹²
remember, b⁸=b*b*b*b*b*b*b*b and b⁴=b*b*b*b
so b⁸ * b⁴ = b*b*b*b*b*b*b*b * b*b*b*b = b¹²
I think I understand 3 but not the rest of them
Answer:
x = 2
Step-by-step explanation:
6(x-4) + 7 = -5
6(x-4) + 7 - 7 = -5 - 7
6(x-4) = -12
6(x-4)/6 = -12/6
x - 4 = -2
x - 4 + 4 = -2 + 4
x = 2
