Answer:
a=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11a−(4a−7)=77
11a+−1(4a−7)=77(Distribute the Negative Sign)
11a+−1(4a)+(−1)(−7)=77
11a+−4a+7=77
(11a+−4a)+(7)=77(Combine Like Terms)
7a+7=77
Step 2: Subtract 7 from both sides.
7a+7−7=77−7
7a=70
Step 3: Divide both sides by 7.
Thus a = 10

Answer:
1.7689 (rounded to 4 decimal places)
Step-by-step explanation:
Let the number we are seeking be "x", thus we can write the equation as:
Since we have raised "x" to the "10th power", to get "x" back again, we need to take 10th root. Same goes for right side, we take 10th root of 300. We will get our answer. The process shown below:
hence, 1.7689 raised to 10th power will give us 300
