PLEASE ANSWER QUICK THIS IS URGENT

Estimate (this was the question for part A)
10/12 - 3/8
using benchmark values. Your equation must show the estimate for each fraction and the final estimate for the expression.

(this is part B) Solve 10/12 - 3/8 Show your solution as an equation.

Calculate the difference between your estimate in Part A and the actual value you calculated in Part B. Be sure to show this solution as an equation.

Based on this difference, do you think your estimate for Part A was reasonable? Explain.

answer: c i think

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
