8*2^{3x}-32=0

Solution

8 \cdot 2^{3 x} - 32 = 0

Solution

x = \frac{2}{3}

+1

Decimal Notation

x = 0.66666 \dots

Solution steps

8 \cdot 2^{3 x} - 32 = 0

Add

32

to both sides

8 \cdot 2^{3 x} - 32 + 32 = 0 + 32

Simplify

8 \cdot 2^{3 x} = 32

Divide both sides by

8

2^{3 x} = 4

Apply exponent rules

3 x = 2

Solve

3 x = 2 : x = \frac{2}{3}

x = \frac{2}{3}

5(7^{(2x-1)})=7(5^{(x+2)})

5 (7^{(2 x - 1)}) = 7 (5^{(x + 2)})

3^{2x-1}=9sqrt(3)

3^{2 x - 1} = 93

5^{x} = 5^{2}
