Answer
- A. x = - 2 the answer B. x = 0 the answer C. x = 0 the answer
- A. Wrong solution x = - 1 the answer B. Correct solution x= - 1/4 the answer
- A. x = 1/7 the answer B. Missing! 32x+1^ = ?missing data C. Step 3 : x = 2 the answer
- Yes, it is true that if both sides of the exponential equation have different bases, logarithms are used to solve the exponential equation.
- A. x = (log 7/log 4) - 1 the answer Explanation
- A. 32x + 2^ = 3x Step 1 : 32x + 2^ = 3x Step 2 : 2x + 2 = x Step 3 : 2x - x = - 2 Step 4 : x = - 2 the answer B. 52x-1 = Step 1 : 52x- 50 = Step 2 : 2x - 0 = 0 Step 3 : x = 0/ Step 4 : x = 0 the answer C.3x+1= Step 1 : 3x+3^0 = Step 2 : x +0= Step 3 : x = 0 the answer
- A. Wrong solution 16 x+1= (1/4)x-^1 Step 1 : (4^2 )x+1=(4-^1 )x-^1 Step 2 : 2x+2= - x+ Step 3 : 2x+x=- 1 - 2 Step 4 : 3x = - 3 Step 5 : x = - 3/ Step 6 : x = - 1 the answer B. Correct solution x =-1/4 the answer
