D. Translate into an equation (3 x 30) + (30 - 10) + 30 = m
Wait isn't this the same question before?
Answer:
What are the laws of indices?
Laws of indices provide us with rules for simplifying calculations or expressions involving powers of the same base. This means that the larger number or letter must be the same.
Step-by-step explanation:
The first law: multiplication
The second law: division
The third law: brackets
Negative powers
Power of zero
Fractional powers
The answer is
D= logbase1.06 2=t
If you compute it, you will will get 11.89 years which rounded to 12 years
Answer:
b = 16
Step-by-step explanation:
16*x + b*x + 4 = 0
Solving for x we get:
x₁,₂ = - b ± √ b² - 4*a*c ] / 2*a (1)
If we take a look to the square root
√ b² - 4*4*16 = √ b² - 256
if we make √ b² - 256 = 0
b² = 256 ⇒ b = 16
Then equation (1) becomes:
x₁,₂ = ( - 16 ± 0 ) / 32
x = - 1/2
