Math Problem Statement

Solve for x if 32(4) 2𝑥= (8) 3 (4 x+1 )

Solution

To solve the equation, we first need to express it correctly:

Given equation:

32(4)2x=83×(4x+1)32(4)^{2x} = 8^3 \times (4^{x+1})

Step 1: Simplify the equation

We know that: 32=25and4=22and8=2332 = 2^5 \quad \text{and} \quad 4 = 2^2 \quad \text{and} \quad 8 = 2^3

So, let's rewrite the equation using base 2: 25×(22)2x=(23)3×(22)x+12^5 \times (2^2)^{2x} = (2^3)^3 \times (2^2)^{x+1}

Simplify the exponents: 25×24x=29×22(x+1)2^5 \times 2^{4x} = 2^9 \times 2^{2(x+1)}

25+4x=29+2x+22^{5+4x} = 2^{9 + 2x + 2}

Simplify further: 24x+5=22x+112^{4x+5} = 2^{2x+11}

Since the bases are the same, we can set the exponents equal to each other: 4x+5=2x+114x + 5 = 2x + 11

Step 2: Solve for xx

Subtract 2x2x from both sides: 2x+5=112x + 5 = 11

Subtract 5 from both sides: 2x=62x = 6

Divide by 2: x=3x = 3

So, the solution is x=3x = 3.
