Solution

4^{y + 1} + 4^{y} = 320

Solution

y = 3

Solution steps

4^{y + 1} + 4^{y} = 320

Factor

4^{y + 1} + 4^{y} : 5 \cdot 4^{y}

5 \cdot 4^{y} = 320

Divide both sides by

5

4^{y} = 64

Apply exponent rules

y = 3

Popular Examples

4^{4 e} = 8^{e - 3}

950=850(1.015)^x-550

950 = 850 (1.015)^{x} - 550

e^{x + 5} = \frac{1}{e}

4^{7 x + 4} = 3

27^{x-5}=(1/3)^{x-1}

2 7^{x - 5} = (\frac{1}{3})^{x - 1}
